ReadyBoost Q&A


Back in April, I posted a blog entry on the ReadyBoost feature – the Windows Vista feature that allows you to use a USB key as virtual memory in order to enhance performance. While I originally intended the post to be an overview of ReadyBoost, it proved quite popular and garnered quite a few questions seeking more detail. I apologize that it’s taken this long, but I’ve finally tracked down “the man” who could provide the answers – Matt Ayers, who is the Program Manager in the Microsoft Windows Client Performance group and basically owns the ReadyBoost feature.

Instead of updating the original post, I created this new post entry that will be the home of the Q&A I receive. That way, people won’t have to wade through opinions and comments and can come to this post to see only Q&A. 

Note: Matt will be speaking at Tech*Ed where he will present a session on on Vista Perf Improvements (ReadyBoost, ReadyDrive and SuperFetch – CLI312)

From Matt Ayers:

“I’m the Program Manager in the Microsoft Windows Client Performance group and own the ReadyBoost feature. I wanted to give some offical answers based on the excellent questions and discussions that I’ve seen in this blog, to date. Also, I’ll be using this as a starting point for the official ReadyBoost FAQ.

Overall, as many posters have pointed out, the feature is designed to improve small random I/O for people who lack the expansion slots, money, and or technical expertise to add additional RAM. As y’all know, adding RAM is still the best way to relieve memory pressure.

Thanks, again, for your interest, questions and ideas.”


 

Q: What perf do you need on your device?
A: 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for 512K random writes

Q: My device says 12MB/sec (or 133x or something else) on the package but windows says that it isn’t fast enough to use as a ReadyBoost device… why?
A: Two possible reasons:

  1. The numbers measure sequential performance and we measure random. We’ve seen devices that have great sequential perf, but horrible random
  2. The performance isn’t consistantly fast across the entire device. Some devices have 128M of lightning fast flash and the rest of the device is really slow. This is fine for some applications but not ReadyBoost.


Q: What’s the largest amount of flash that I can use for ReadyBoost?
A: You can use up to 4GB of flash for ReadyBoost (which turns out to be 8GB of cache w/ the compression)

Q: Why can’t I use more than 4GB of flash?
A: The FAT32 filesystem limits our ReadyBoost.sfcache file to 4GB

Q: What’s the smallest ReadyBoost cache that I can use
A: The smallest cache is 256MB (well, 250 after formatting). Post beta2, we may drop it another 10 MB or so.

Q: Ok… 256M-4GB is a pretty big range… any recommendations?
A: Yes. We recommend a 1:1 ratio of flash to system memory at the low end and as high as 2.5:1 flash to system memory. Higher than that and you won’t see much benefit.

Q: Isn’t this just putting the paging file onto a flash disk?
A: Not really – the file is still backed on disk. This is a cache – if the data is not found in the ReadyBoost cache, we fall back to the HDD.

Q: Aren’t Hard Disks faster than flash? My HDD has 80MB/sec throughput.
A: Hard drives are great for large sequential I/O. For those situations, ReadyBoost gets out of the way. We concentrate on improving the performance of small, random I/Os, like paging to and from disk.

Q: What happens when you remove the drive?
A: When a surprise remove event occurs and we can’t find the drive, we fall back to disk. Again, all pages on the device are backed by a page on disk. No exceptions. This isn’t a separate page file store, but rather a cache to speed up access to frequently used data.

Q: Isn’t user data on a removable device a security risk?
A: This was one of our first concerns and to mitigate this risk, we use AES-128 to encrypt everything that we write to the device.

Q: Won’t this wear out the drive?
A: Nope. We’re aware of the lifecycle issues with flash drives and are smart about how and when we do our writes to the device. Our research shows that we will get at least 10+ years out of flash devices that we support.

Q: Can use use multiple devices for EMDs?
A: Nope. We’ve limited Vista to one ReadyBoost per machine

Q: Why just one device?
A: Time and quality. Since this is the first revision of the feature, we decided to focus on making the single device exceptional, without the difficulties of managing multiple caches. We like the idea, though, and it’s under consideration for future versions.

Q: Do you support SD/CF/memory stick/MMC/etc.?
A: Mostly. In beta2, we added support for a small number of SD/CF cards on internal USB2 & PCIe busses. RC1 has a much broader support range.

Q: Why don’t you support SD on my USB2.0 external card reader?
A: We unfortunately don’t support external card readers – there were some technical hurdles that we didn’t have time to address. In general, if a card reader shows a drive without media in it (like a floppy drive or CD ROM does), we can’t use it for ReadyBoost.

Q: Will it support all USB drives, regardless of how they are ID’d to the OS (“hard disk drive” or “Device with Removable Storage”)?
A: We have no way to tell what is on the other end of a USB cable so we do some basic size checks (since no one has a 200GB flash device 😉 ) and then perform our speed tests. HDD will not, however, pass our speed tests, and there is no benefit to using a USB HDD for ReadyBoost.

Q: Can you use an mp3 player to speed up your system?
A: Not currently. MP3 players use the ‘plays for sure’ interfaces to expose themselves to Windows. We require that the device appear as a disk volume. These aren’t currently compatible.

Q: How much of a speed increase are we talking about?
A: Well, that depends. On average, a RANDOM 4K read from flash is about 10x faster than from HDD. Now, how does that translate to end-user perf? Under memory pressure and heavy disk activity, the system is much more responsive; on a 4GB machine with few applications running, the ReadyBoost effect is much less noticable.

Q: I can’t get my device to work with ReadyBoost… can I lower the perf requirements?
A: Unfortunately, no. We’ve set the perf requirements to the lowest possible throughput that still makes your system faster. If we lowered the perf requirements, then there wouldn’t be a noticeable benefit to using ReadyBoost. Remember, we’re not adding memory, we’re improving disk access.

Q: Which manufacturers support ReadyBoost?
A: Well, I hope that all of them do, eventually. Right now, we’re working with manufacturers to create a program that will allow them to identify ReadyBoost capable devices on their packaging.

    Hi Tom, I’ve a little question, how can I find a list of Windows Vista languages, you know Microsoft accepted "Persian" instead of "farsi" and I expect; in Vista, Microsoft will name my language Persian and not "farsi", anymore!, it make me very happy to see Microsoft such perfect ! but unfortunately one of my friends told me he saw "farsi" is still used in Vista Beta (I think Beta1). Now, is there any way to find the list of Vista’s pri. languages? and if it’s still "farsi" in Vista, how can I convince you (I don’t really think it’s needed because Microsoft had accepted it : (Note3)>http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/nls_61df.asp) Best Regards … Sassan [iranssn.at.yahoodotcom] …

    Hi,

    What about pc’s with a memory size of 4GB for example? Can I decide to use a part of my motherboard memory as virtual memory istead of a USB storage device?

    Can some one tell me more about this issue.

    Thank you,

    I’ve not noticed any difference with my SanDisk Cruzer Mini 512MB stick plugged in, with it set to use all of the stick’s capacity.  I’ve got 1GB of RAM, so I imagine Vista is pretty much constantly paging.  I have two raid0 arrays, one with a couple of 200gig Seagate 7200rpm drives, and the other a couple of 80gig Western Digital 7200rpm drives.  I have set aside the first 1.5GB or so of the Western Digital array for my pagefile.  This means that the pagefile is residing only on the first 768MB or so of each of those drives.  Out of 80gigs, 768MB is a pretty small distance for the heads to be travelling.  I have the OS installed on a 30gig partition of the Seagate array, the first partition of that one.  All my programs are installed on the same 30gig partition.  I keep most of my data on the remaining ~370gig partition, as well as any games.  The remaining ~158gigs of the other array is mainly for backups and old data, etc, so that array with the pagefile is used 99.9% of the time just for paging activity.  It pretty much sees no use other than paging in my day to day activities.  This gives that array a pretty much ideal scenario for paging.  The area it has to access is very, very small, and it does nothing else so there is nothing else competing for access to it.  And the OS and programs etc are all on their own on a seperate array, so their activity has zero impact on paging performance.

    Now, having set all that out, I’ve got to say that I would not be able to tell you whether or not I’ve got the USB stick plugged in and set to ReadyBoost duty.  I can’t tell any improvement has appeared after plugging it in and setting it for ReadyBoost with all its capacity.  It’s probably safe to say that this raid0 array for paging sees at least 80-100MB/s in sequential read/write access.  And I fail to see how even the worst-case scenario of random access *just for paging* is going to slow it down to the point where the USB stick is going to be beneficial.  The absolute worst random load you could put on it is still only going to be in that small first 768MB of each drive in the array.  I can’t imagine the access time in that small area is going to hurt the performance enough for the USB stick to make a difference.

    I can understand if you’ve only got a single drive in the machine, and thus have the same drive doing paging duty and the rest of the file access duty, and have a USB stick help out in that situation.  The drive is going to be experiencing a lot more head movement since it is being used for a lot more than just paging.  And it could be moving the heads throughout the whole span in that case.

    So, should I really be seeing any difference in my case?  With a more or less dedicated raid0 array for paging?  Because I can’t tell the difference at all.

    Could you list a few devices that actually work i know my ipod shuffle works, sorry for mentioning that company, and i  however my brand new sd card, 2gb, does not work, I would love to buy a 2/4 gb usb2.0 flash memory stick, but I do not want to buy it unless i know it will work, I will install Beta 2 this weekend, currently I am running 5308.

  5. MVPKenLin says:

    Thanks Matt Ayers giving us this Q&A, after reading this, I got few questions,

    1) about 4Gb of Flash, I heard someone format it as NTFS. By doing so, will it support higher Gb of flash?

    (Source from a test in http://www.msblog.org/?p=716)

    2) ReadyBoost is "cache" of the paging-file on disk? That means it will write to flash(as cache) then to disk? But it reads from flash then from disk(if no found from flash)?

    3) > In general, if a card reader shows a drive without

       > media in it (like a floppy drive or CD ROM does),

       > we can’t use it for ReadyBoost.

    I don’t understand(may be my bad english). If my computer is showing them as removable storage Drive (H:, I:, J:, K:…etc, my one is USB external multi-card-type reader), but not floppy drive or CD ROM, Could my external Reader works with SD?

    4) Do you(Matt Ayers) have blog? I would like to contact u, cause I am looking for a topic to speak in my local TechEd

    hello i bought a pny 2.0 1gb flash drive  to use just for readyboost, i formated it with both fat32 and ntfs but it tells me that "this device dose not have the required performance charateristics for use in speeding up your system" what could be the problem thanks.

  18. Plenty of MP3 players that don’t support PlaysForSure id to Windows as a drive letter; if they’re Flash and they have free space will they work for ReadyBoost? (I know you can block flash drives you don’t want to use, before anyone frets about it).

  19. re: Windows Ready Boost – Windows Vista

  20. Shorty-CM says:

    well, a couple weeks ago I wrote a whole big long thing about how I doubt that ReadyBoost will perform better than a dedicated raid0 partition/drive that is used for nothing but pagefile duty.  Don’t know what happened to that post.  Anyways, yeah, I doubt it would be faster than a raid0 drive that is doing nothing else but pagefile duty.  Though I can see how it might help out a lot in a system that only has a single HD that is being used for OS, programs, and pagefile, all at the same time.  Somehow I doubt that a raid0 drive that gets a sustained 85MB/s is going to be slower than a USB flash drive, especially considering the drive’s heads will only be moving the very small distance of the first 2-3GB of the array.  In that situation the access time is going to be very quick, and obviously the flash drive isn’t going to touch the transfer rate.  Yes, we’re talking about relatively random, and small, transactions.  But we’re also talking about a very small portion of the array being used.  Access time will still be slower than the flash memory’s, but I doubt it is going to matter.  Would be nice if we had some kind of stand-alone benchmark to test devices, rather than only the one that is built into Vista.  Would make shopping for a suitable flash drive, for instance, very easy.

  21. Zack Uribe says:

    Will it make any difference to ReadyBoost performance if you have the USB flashdrive set up to "Optimize for 1) Quick removal or 2) Best Performance/

    Thanks,

    Zack

    p.s. Please get more info out about PowerBoost, this is the most info I could find on the net, and there is no PowerBoost entry in the Help file(I had disabled teh service which controls PowerBoost so was having tons of trouble.)

    It would be nice if the service had a description mentioning PowerBoost.

  22. Promy says:

    I was wondering…

    Would it be faster to use this ready boost on a CF card connected to and IDE interface?

  23. Chuck Naslund says:

    I purchased from Fry’s a Memorex 512MB USB 2.0 Flash Drive for 18$ the other day. It was tested by Vista Beta 2 when inserted and works great as a ReadyBoost Cache.

  24. Urchent says:

    I’m Using a SimpleTech Bonzai USB SD card reader. I have tried sizes from 512 MB to 4GB all work for ready boost I have used mostly SimpleTech SD cards as well as SanDisk. I was surprised to see how much activity it get’s since my system already has 4GB of system ram I have however long disabled the page file on the HDD. HDD may be fast for a lot of things but really can’t take the constant small IO often needed for page files (even if using the beginning of the drive or in raid 0) The flash drive although does not have the ability to write a few hundred MB of data fast does have a near 0 wait to begin write. The things it get’s used for, it is done doing with it "slow speed" before a HDD has been able to move its head to start writing and the biggest benefit is from reading not writing on nearly all flash drives reading is a lot faster and further improves things. I plan to attach a spare 4GB SD card to a unused port on the back of my computer and just forget about it. As for NTFS (this may be new to beta 2) it used cards formatted NTFS and FAT32 identically. Fat32 is that way all card come from the store but you can format them NTFS if needed for compression file permissions etc. FAT32 cannot make a file over 4GB that’s one of its limitations. NTFS however can make files much much larger thought I don’t have any cards over 4GB to test the file limit at this time I suspect it would work ok. However a note on that. You are not adding ram for once size is not everything. Your using this disk for small files and IO a few K at a time if all goes well. These small files are why Flash is better that HDD if large IO is needed the HDD is still used and preferred. That said 1-2GB is plenty for most applications and you’ll see huge diminished returns approaching 4gb or higher at least with today’s drives and technology, and for some time to come. As for some drives not appearing fast enough you do realize if the drive is too slow even with 0 wait to write it will be slower that the average HDD hence no "boost" at all since this is not adding ram but rather IO speed is more important that capacity. This is the reason for the speed limit. a good point was the one about a trick many drives try using two speeds of flash some fast flash and a bunch of slow flash. the fast is used first to make the drive look fast when you save a file to it then quietly and slowly moved to the bulk slow stuff. most of the time this is not an issue and helps keep the drives really cheap. however for this IO type work Vista needs any part of the drive it may need to be just as fast. this is why a lot of devices will not work. SD and CF cards in readers that support the proper profiles such as the one i mentioned should normally be ok. SD and CF are normally all same speed flash and all of its normally pretty quick. I saw a question about CF on IDE. That will not give you any improvement actually i doubt it will even work even though it is flash since it’s using IDE to the motherboard Vista will likely think it’s a small HDD and not even offer ReadyBoost for it. even if it did it will be no better the flash itself is the slowest part no flash device yet can use even 1/10th of the USB 2.0 or IDE buss speeds (actually in a perfect world and no USB hubs USB technically could be faster) I hope I further cleared up some questions on an already great article.

  25. Brandon says:

    I have what was supposed to be one of the fastest USB flash drives on the market – the Transcend JetFlash 110 (1GB size). I was puzzled why Vista wouldn’t use it for ReadyDrive until I checked the Event Log for ReadyDrive and saw this:

    The device (JetFlash TS1GJF110) will not be used for a ReadyBoost cache because it does not exhibit uniform performance across the device.  Size of fast region: 120 MB.

    So it looks like Transcend cheaped out in manufacturing and made only 120 of the 1000 megs out of the high-speed material. Sucks for me.

  30. Rik Hemsley says:

    Perhaps the entry on card readers needs revising?

    I’m on Vista beta 2. USB 2.0 is via a NEC PCI card.

    I have a no-name multi card reader into which I’ve inserted a 512M Memory Stick PRO Duo. Vista accepted this and has put a 410MB file onto it.

    I can’t tell if it is actually using that 410MB file, but it didn’t complain at any point.

    BTW it’s a bit annoying that I can’t use a 256M CF card because however I format it, it’s always got slightly less than the required 256M available, so yes, it might be sensible to reduce the requirement by e.g. 20M.

    Hi,

    I would like to know how Vista decides whether the Device is capable for ReadyBoost. Your QA gives a partial answer that "we do some basic size checks and then perform our speed tests" , but is it only the size and speed of the disk device that decides this or any other registry/device setting is present?

    thanks

It may just be the default allocation size that made it work though, for all I know the SD card may have come formatted with some standard allocation size for FAT32. Still, changing the allocation size or the file system may work for others.

    Has Microsoft or its OEM partners expressed any interest in including some internal flash memory with the system out-of-the-box?  This feature is great, but using an external memory stick seems like a hack.  I’d like to see 4GB flash directly on the motherboard for just this sort of thing.  Maybe even skip the USB/PCI bus all together and provide a quick DMA channel between the flash cache and memory.

    Ashok mate, you’d be FAR better off just buying enough RAM.  Even if this works (and I’m very skeptical) you’ll get 10%. Absolute tops. Improvement.

    Is MS going to certify USB drives that are Readboost-capable once Vista comes out?  How much more expensive will they be than regular flash drives.  You can get a two gig flash for less than $40 now.  I hope if they do certify, the price is going to be comparable.

  55. Sefi says:

    In some cases even a slower USB device could help. For example an older notebook with 1G ram and a slow HDD (4200RPM). It these cases you can enable readyboost with a slow device.

    1. Let Vista test is, and check the Do not Retest this device checkbox.

    2. Unplug the device

    3. Go to regedit

    HKLMSOFTWAREMicrosoftWindows NTCurrentVersionEMDMgmt

    4.find the key related to you device (the device  vendor and name is in the key)

    5. Change the follwing values:

     Device Status 0x02

    ReadSpeedKBs 0x1000

    WriteSpeedKBs 0x1000

    6. Plug the device, right click on it to open properties and enable cache.

  56. Jason says:

    My Memorex Travel 1GB doesn’t work either. Maybe I’ll throwdown on a A-Data MyFlash…

  57. I’m running RC1 and have a 256MB USB flash drive. 256MB seems small to me for ReadyBoost but I figure every little bit helps so I’ve set it up.

    At first it wouldn’t qualify the drive as able to use ReadyBoost. Not sure but I think it was formated FAT. Anyway I though NTFS might be best so I tried that. Still no go. Then FAT32 and it is working!

    Then I was goofing around and went to FAT and still no go. Then Fat32, still no go. Then NTFS, still no go. FAT32 again and presto!

    So…seems, at least in my case, that if you can’t get your disk to qualify, try NTFS first then immediatly reformat to FAT32.

    The flash disk I’m using is a DANE ELEC (they came in a pack of 4 from Costco)

  58. ranron says:

    I have Vista RC1 and a 4GB Sandisk Cruzer Mini. I got the flash drive when it first came out and it works with ReadyBoost. I have 2 GB of RAM, so running programs, I did not notice much of a performance boost, but when I played a game, it did seem to load a little faster (couple seconds–>Stopwatch), but not much.

    Also I formatted this flash drive into NTFS and it works charmingly.

    i got an Corsair Flash Voyager 1024MB USB2.0 13/19MB sec. it says that it isnt qualified ?????

    i cant understand that, cause this is an very fast usb stick.

    any ideas ?

    i am running vista rc1

  60. Shorty-CM says:

    as MS says, lots of "fast" sticks use a combination of a smaller portion of very fast flash, and a larger portion of slower flash, so perhaps that’s the case with that stick.  And don’t forget, sequential transfer rate isn’t what’s important for this application.  It’s how fast it is at random 4KB accesses.  Being fast at transferring large files back and forth isn’t the same as quickly transferring large amounts of 4KB blocks.  This is why ReadyBoost can be so helpful, because hard drives typically suck at very small, very random transactions.  But flash can be very fast at that type of access.

  61. Bård Tommy says:

    yes, but this is not the case

    http://www.pcstats.com/articleview.cfm?articleid=1706&page=2

    there you can se an benchmarktest with sandra 2005

    Buffered Read : 17 MB/s

    Sequential Read : 17 MB/s

    Random Read : 14 MB/s

    Buffered Write : 2641 kB/s

    Sequential Write : 11 MB/s

    Random Write : 7 MB/s

    Average Access Time : 15 ms

    isnt that qualified ?

  62. Shorty-CM says:

    I think you’re missing the point entirely.  MS benchmarks the stick using 4KB reads, no more, no less.  It randomly reads 4KB blocks from all over the stick.  And if it can’t do enough of those reads per second, it fails the stick.  It doesn’t matter what any other benchmark program says the stick can do.  All that matters is whether or not the stick can do enough random 4KB reads per second to meet what MS says is enough per second.  Transfer rate is almost irrelevant.  All that matters is number of 4KB reads per second.  This is almost all about access time, not transfer rate.  The fact that your stick can do 17MB/s reads is meaningless when it comes to ReadyBoost.  And it says right there that its access time is 15ms, that is INSANELY SLOW for flash drives.  This value should be well under 1ms, well, well under.  15ms means that the most transactions it could do per second is 66.67, this is even slower than some hard drives.  And the whole point of ReadyBoost is to be faster than hard drives for this type of usage.  You obviously need to scroll back to the top of this page and read the questions and answers again.  They already contain the answers you need.

  63. RickW says:

    The Apacer Handy Steno HT203 1Gb scores as follows:

    The device ( USB FLASH DRIVE) is suitable for a ReadyBoost cache.  The recommended cache size is 899072 KB.  The random read speed is 4146 KB/sec.  The sequential write speed is 6284 KB/sec.

    This is FAT with a really small block size.

  64. Pres says:

    I agree.  It doesn’t matter what any benchmarking utility says.  Sisoftware Sandra would freeze when benchmarking my A-data Myflash 256 drive but it works with readyboost.  HDtach puts the access time at .8ms.

    Just wondering if you can software RAID usb in vista, would be great raiding 4 usb pens and using them for readyboost

  70. Shorty-CM says:

    you wouldn’t gain anything.  ReadyBoost is essentially doing random 4KB reads.  RAID0, which I guess you were referring to, wouldn’t speed that up at all.  It would be using much larger units to stripe with.  The only way it could be made faster is if ReadyBoost were able to use more than one stick, itself.  The MS guys have said they have thought of that scenario, too, but it was too complex to implement for the first release of Vista.  So perhaps in a future release we’ll see multiple sticks being available for ReadyBoost.

  71. Dave says:

    Ok, thanks for the reply, I was also wondering if there are any plans or have already been developed for say, something like a USB adapter which can take, say, a So-DIMM and has battery backup to make it non volotile, these would be great for USB storage and would get a max speed of 33mb/s for writing at reading.

  72. Shorty-CM says:

    well, you can get devices that look like an IDE hard drive  to the OS that actually take ram, which is similar to your idea.  But they’re going to be faster, since they’ll be using IDE instead.  They’re not exactly cheap, though.  Usually called a solid-state drive.  Used to be really expensive, but now you can get one for something resembling a reasonable price.  Probably more than worth it if you have the need for one.

  74. IS there any easy method to locate the page files (and any other MS files) at an hard location within a disk volume, that would minimized seek time?  If so, how how could one keep optimazation(sp) over disk defraging?  If so, how could one calculate a new suggested hard location as the usage increases.  Could somebody point me to any white papers?

    Also, does it make any sense to place Temp files and folders on a flash drive.  What would the cost of reformatting per start/restart would be?  Would there be any unstablizing of the restart of applications?  Does anybody have any Guidelines?  

  75. Shorty-CM says:

    optimal hard drive pagefile would be on a completely seperate hard drive, right at the very start, which is the fastest portion of the drive.  So that pagefile access doesn’t impact your hard drive access, at least not directly.  They’ll still have to live with each other on the PCI bus, but they won’t have to compete for the same drive head(s).  Naturally, the best thing to do in all cases is install more ram if you can.  ReadyBoost just provides extra help if that is something you can’t do.  Obviously reducing pagefile access as much as possible is a better solution.  Once you’ve done that, you can worry about making pagefile access better, via ReadyBoost and other steps.

  76. Depending on who talk to, people will tell you how happy/unhappy they are with current Windows Vista…

  77. TAG says:

    Why ReadyBoost create this ReadyBoost.sfcache FILE on this  flash disk file system ?

    You have full control over file system and all it’s datastructures. It was easy to put cache only in free sectors. Anyway you will be able to validate that data in thouse sectors are legit (not overriden by other non-ready boost aware OS) becouse of encryption.

    This will also allow users to not delete entire file then then need more space but simply use flash disk as is and override data on demand.

    Probably I need to file a patent on this. 😉

  78. KH Lee says:

    I sucessfully enabled readyboost drive thru. Card Reader – SD/MMC. I think it’s somewhat different from your comments. Does it mean Window vista allow USB card reader?

    Also, I checked flash card performance test results which are logged on window vista. I see performance difference between direct SD attached to PC and SD attach thru. USB.. a bit confusing…

  79. Rajo says:

    For Bård Tommy: I have this flashdrive also… Its problem is that it’s very fast in sequential r/w, but  SUCKS completely at random read/write, which renders it effectivelly unusable for ReadyBoost.

  80. Alex says:

    Hi, thanks for clarifying. Since it’s possible to surprise remove at any time, I kind of assumed it only dealt with executable pages, which are dumped to flash, but can be fetched back from disk if the flash becomes unavailable.

    Using it as a cache for *all* data makes even more sense.

  81. Shorty-CM says:

    I don’t think windows treats executable code pages or data pages any differently.  It just concerns itself with whether or not pages are getting accessed, regardless of type, and makes its decisions based on that access.  As for surprise removal of the device, all pages on the ReadyBoost device are also on disk.  The ReadyBoost device is just a cache of what’s on disk.  So it won’t matter if/when you yank the device, nothing bad’s gonna happen.

  82. joey says:

    i would love to know if there are some performance counters that i could use to see the cache hits or performance increase from readyboost.  it would also be fun to stick something on the sidebar and show people the benefits in real time.

    I was thinking of using the CF/SD card reader built in to my next laptop, rather than using the USB ports. That way it can be safe and out of sight and permanently attached.

    I also want to format it as NTFS and put my pagefile on it. Will just have to see if it is fast enough for both simultaneous writes and large bandwidth sustained writes.

  84. readyboost makes it faster — maybe

  85. herndonken says:

    For those who asked about PCMCIA or Cardbus, it appears that Readyboost in RC2 does NOT provide support for 32 bit Cardbus flash readers fitted with compact flash memory cards.

    Tested with the Lexar high speed 32 bit cardbus reader and the extremely fast ProMax 2 Gb ATP CompactFlash card. As a matter of fact, the readboost testing and menu options are not present on the properties/hw submenus.

    Note that the ProMax CF card work perfectly with ReadyBoost using an USB 2.0 CF reader.

    I have heard that there is a way to manually force the use of readyboost on a drive through a registry change.  Anyone have any ideas on how to do this?  Would this work in the case of the lack of support for 32-bit cardbus?

    ReadyBoost is pure marketing BS.

    I’m running Vista RC2 with 1GB, and I have a 2GB Kingston DataTraveler Elite (one of the fastest USB flash memory sticks).

    I plugged in to a USB2 port directly to my motherboard. I set ReadyBoost to the Windows recommended value of 1880MB and performance *plummeted*.

    Media Centre used to be perfectly smooth. Using ReadyBoost, it stutters and is unwatchable. I *cannot* use ReadyBoost whilst watching TV on the media centre.

    Readers, please don’t think that ReadyBoost will solve any performance problems for you, or act as extra RAM. It will do effectively nothing but use up your USB memory. Forget about it until the next generation of fash flash disks come out:

    The ReadyBoost feature will reveal its full potential once combined with mainboards that contain embedded flash memory chips. Using large quantities of flash (2-4GB) will enable the system not only to boost its speed, but to cold start boot alltogether from flash. As it is, for ReadBoost to be effective it requires top-notch NAND flash (preferably dual channel), or the new type OneNAND that is developed by Samsung and STMicroelectronics.

    Using ReadyBoost on a 4GB iPod Nano. At first the device was too slow for ReadyBoost, but after a defrag it works great. I have 1GB of RAM and I used to notice that icons and thumbnails would take a few milliseconds to show up, but now they are just there. Great work!

    I’m wondering though…can I restart without removing the device? Is that safe? I ask because I’m curious to know if the sf file remains on the iPod during a restart.  I know Vista destroys the file if I safely remove the device.

    Actually I’ve never restarted without safely removing the device, because I’d rather not risk losing 3GB of music.

    If the sf file is destroyed after restarting, maybe it’d be a good idea to have it persist…or at least let the user elect to have it so?

    Nice work anyway!

    Hi guys.  Can a solid state disk, attached internally via an IDE or SATA interface be used as a ReadyDrive?  This question has been asked in the forum, but not answered.  We just installed Windows Vista RC2 and our solid state disks (SSDs) from PQI (using Samsung NANDs) go out to customers the same day they come in, so we have not been able to test weather Windows Vista will use these IDE or SATA flash disks as readyboost.  Is ReadyBoost limited to a USB interface?  Or can Vista tell that the disk is made of flash?  I’m hoping the latter, especially due to hybrid support.

    We sell SSDs from 4GB to 32GB (and 64GB coming soon.  Even an SSD with IDE on one side, and SATA on the other!) .  PQI just came out with a USB 2.0 SSD called a "DOM" for Disk on Module.  It plugs into your motherboard’s internal 10-pin USB header and will surely work for ReadyBoost and is significantly faster than any other flash stick I have seen.  22MB/s read, 17MB/s write.  We’ll be getting one for ourself for testing in the next couple weeks.

    Check out the SSDs at http://www.dvnation.com/nand-flash-ssd.html .  We also have a message board.

  96. dvnation.com says:

    Alternatively, you could buy a 32GB Solid State Disk just to install Windows and its swap file.  That should be enough as long as you install all your programs and data files to a separate hard disk.  This way you get super-fast OS performance.  Even a 15MB/s SSD will boot Windows Vista 21% faster on a laptop.  The new 32GB SSDs operate at 24 – 32MB/s so performace will be even better.  <1ms access times seem to give a better performance than higher sustained throughput, as evidenced by our Microsoft Man’s saying its the 4K random reads that are cached and improve performance.

  108. RJ says:

    There has been some debate on weather ReadyBoost will speed up boot time.  The answer is yes.  You just have to give it time.  After installing my ReadyBoost SSD, I rebooted a couple times with NO decrease in boot time.  Then I let the system sit idle for a long time. I came back in the room and even though I hadn’t opened even one program, Windows was thrashing the hard disk, taking the time, evidently, to cache to the ReadyDrive.  The next time I booted, the system booted 3 seconds faster (11.5%).  I bought the internal USB SSD at http://www.dvnation.com/nand-flash-ssd.html .  It is much more than $40, but it is also significantly faster than external sticks and works great.

    The guys at DV Nation had the same experience and have a some good information at http://www.dvnation.com/windows-vista-readyboost-readydrive.html .  There is a link there to a forum about solid state disks as well.

    I think this solution should boot windows faster than a hybrid drive, considering the capacity of compatible sticks is 2GB to 4GB, and the flash memory on a hybrid drive (when they come out next year) is only 128MB or 256MB, and I have only heard of comparitively slow laptop drives with that tech.

    Pleasure writing to you at this moment of the day,I am Mrs.Fatim Ali the Personal Assistance To The director Incharge of files and Company Secret Vault where deposited items are kept. I deem it fit to contact you regarding to a transaction that will favour both of us at the end.I got your contact in my search for a reputable and reliable person to help me claim the fund in question. I discovered the sum of ($30M)Thirty million United States Dollars belonging to a deceased customer of this Security Company.

    The fund has been lying in a suspence Vault as a family treasure without anybody coming to put claim over the money since the Owner late Coporal Fredrik Whisky,from Sierra-Leone, who was involved in the December 25th Benin plane crash,here is the air crash

    website. http://www.cnn.com/2003/WORLD/africa/12/26/benin.crash/index.html

    The said Fund registered as (FAMILY TREASURE) is now ready for transfer to our foriegn Vault account whose owner will be portrayed as the beneficiary and next of kin to the deceased customer of the Security Company. The foriegn Vault account owner will impost himself/herself as the next of kin to the deceased and respond positively like a true next of kin who wishes to speed up the release and transfer of his inherited (FAMILY TREASURE).

    If the over due family treasure if not claimed by the end of next quarter, the government of the Federal Republic of Benin will take over the ownership of the treasure in line with the Federal Edict Act of 1979. I do not want the government to take over the ownership of this Treasure, that is why I contacted you for us to do the deal together, so that i will portray you as the bonafide next of kin to the deceased whose name is Coporal Fredrik Whisky.

    If you accept to carry out this project with me, i will offer you 40% of the total sum, while I take 60% of the total sum.Upon your acceptance to do this deal with me, i will jointly effect the transfer within eight working days.Be rest assured that, this transaction carries no risk and no extra responssibilities on your part, except the above mentioned roles and normally you will be required to maintain absolute information and absolute secrecy throughout the duration of this transaction, because discussing it with a third party might jeopardise the entire transaction.

    I am looking forward to receiving your interesting response on this project as this will greatly enrich both of us at the end. Your acceptance email should be sent to my Private Email Address:(mrs_fatiz01@myway.com)

    Guys as a company wishing to take advantage of readyboost when we eventually roll it out we purchased a number of 2GB USB drives that we know to be compatible with ReadyBoost and the results so far seem to indicate that  you should not use FAT32, either with the "Performance" policy against the device or the "Optimise for quick removal" – write performance in all cases so far is far worse than FAT. This probably won’t be a huge difference to ReadyBoost since it’s testing (I presume) *read* performance. But given that read performance doesn’t change much with either FAT or FAT32 I’d recommend for the time being sticking with FAT. I’ll be happy to upload the final results – it’s hardly exhaustive but I’ve tried out about 5 key rings so far.

    I used both a 512Kb Kingston SD card and a 4.0 Gb Sandisk Cruzer micro and ReadyBoost works with both (one at a time). However I realized a very annoying problem with readyboost in two laptops (a Thinkpad T43 and a no-brand AMD athlon 3000+): Vista seems to freeze for some miliseconds each second. I tried to copy large files to the sandisk and to the SD card and when writing or reading from the USB pen or from SD card there is no freeze at all. The problem only happens when the media has readyboost enabled or the readyboost service is Started.

I only used to use it for remote access to work and for web browsing so I decided to put Vista Ultimate on it about a month ago (it used to run windows 2000) – I was actually quite pleased with how fast Vista is on quite modest hardware.

    Readyboost option popped up just fine when I inserted the card and it gave me the option of using the whole 4Gb which I thought was a bit wasteful so I just used 2Gb.

    It’s a revelation! The system is now just so much more responsive. Clearly my PC is short on memory. I know this, but I don’t want to add more because its an old PC. Running Vista on it now feels really nice though. Brilliant feature.

    I user USB2 SATA HDD for Readyboost with NTFS File System, 4090 offered size. Write and read speed at this hardware is 16MB/s.

    I tested it with Reliability and…. MMC profram integrated in Vista, and this HDD solution is much faster then I use a high speed USB key.

    You can test it when your Vista started with desktop, then run Reliability tool, scroll down Disk option, and short the opened file by location, there you can see X:Readyboostsuperfetch file sg. like that. You can see how many bytes are written and readed /s.

    With USB HDD data speed is 9MB/s-35MB/s

    With USB key (4GB high speed) is 1MB/s-5MB/s

    So, consider that you buy an expensive 4GB USB key or, for this amount you can buy 250GB sata 300MB/s HDD.

    If you want to find out the speed of the memory test just run regedit and goto and find your device underneath:

    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionEMDMgmt

    There’s a read and a write number, so if your usb memory is too slow you know how slow..  You can of course change these values and set the DeviceStatus = 2 to get it working but that defeats the purpose of the performance increase..

    I tried a few memory sticks and the interesting test was that my 35 dollar GeekSquad 2gb beat out the 60 dollar Micro Cruzer 1gb by a mile..

    I have a question though, why doesn’t Vista support multiple flash drivers?  Couldn’t Vista use them in a Raid configuration, writing 1/n of each chunk to each drive?

    Also, is it possible for developers like myself to create our own ReadyBoost software with improved functionality?

    Btw, this is my first week with Vista and I’m freaking out.  This is the best OS ever.

    I still have one question, which might have been answered. When formatting the flash drive, how big should would make the clusters? I understand that 4KB is all you NEED, but would formatting to 512KB allow for overall better read/write access (at the cost of a few megs of overall usable pagefile size.) I guess my other question would have to be: Does this issue even apply to flash memory?

  172. Clay says:

    I’m using ReadyBoost and I just noticed that my thumb drive (this after about a week of use) started at 256MB (actually lower after formatting 244MB or so) and now it’s at 16.4MB – What’s up with that?

    I’ve read numerous folks talk about using this particular drive with success, also the 2GB version as well.  So I know it is Readyboost compatitble.  Please help!!!!  I’m so very frustrated.

I tried formatting it with NTFS, FAT32, tried increading the allocation size, but no help. Is there any possible solution to this apart from getting a new drive.

I am using Home Premium 64bit edition.

  193. Kevin says:

    I’ve been testing a couple of my USB sticks and I can’t figure out what’s going on.

    First was the PNY Attache 1GB, which gave a read speed of around 5000kb/s, but the write speed was only around 1000Kb/s, causing it to fail the test.

    Next, I tried a Sandisk Cruzer Titanium, and it had a read speed of only 3300Kb/s, yet it’s read speed was around 6500Kb/s.  This drive passed.

    Then, I transfered a single 700MB file to and from both drives, timing their respective performance.  The Sandisk Cruzer Titanium was about a minute faster on the write, which was expected, considering what Vista had tested their write speeds to be.  What blew my mind was that the Cruzer Titanium also transfered the file back to the hard drive faster, suggesting it’s read speed was also faster.  which didn’t coincide with Vista’s speed tests.  

    I’d like to know how Vista measurements differ from my experience, and what would make a slower, cheaper drive post a faster read time than one costing three times as much.

    What I’d like to know is, what is it about the memory in the cheaper PNY stick for it to have suc

  194. Kevin says:

    I made a typo in my above post.  I mean’t that the Sandisk Cruzer Titanium had a WRITE speed of 6500Kb/s.

  195. Kevin says:

    I realize I didn’t even finish my last sentence. :)

    I mean’t to say, What I’d like to know is, what is it about the memory in the cheaper PNY stick for it to have such a (supposedly) faster read, whereas a drive costing three times as much clocks in at 3/5 the speed?

    This is a very informative site, but this information should be posted on Microsoft.com in an easy to find location.

    There is one very valuable piece of information missing that would probably be valuable to everyone:  a list of devices known to work with ReadyBoost, as well as a list of devices known to NOT work.  

    Maintaining this list might be tedious, but Microsoft is really in the best position  to do this.   Even if it wasn’t complete and comprehensive, if it covered the most popular devices it would still go a long way towards making Vista users happier.

    Personally, I’ve bought three seperate devices that others have claimed to work for them that have failed on my laptop–including one device that claimed ReadyBoost compatibility right on the package.

    Readyboost is a good idea but far from great. I would want to see Windows find ANY available storage device and use whatever it can to bring whatever improovement it can get. As Tesco says – every little helps. More and more PCs have multiple hard disks, why not allocate a speed patch area on all disks found to spread the load? Just like RAID but less strict.

  206. Cache Your Page File to Your… iPod Shuffle?

  207. CRS says:

    The only way I’ve been able to utilize Ready Boost to any signifficant advantage is increasing the paging file manually, lets say on a 4GB flash drive, to the minimum at 3799MB and the maximum to 3800MB. Afterward, go to the properties of the flash drive and you will be able to set the cache to upwards of 3500MB. Vista is about four times faster while using the computer. Not too technical but it works and is simple.

  208. Tijn says:

    Hi Tom

    Can’t seem to turn off this ready boost feature, because i’d like to be able to fully use the capacity of my 1gb usb pendrive for datastorage. When i try to put more data on i get error code 0x80070052 and then i checked the properties page and i noticed that the space left on my pendrive is slightly smaller then the minimum required memory for readyboost,which i can’t seem to change.

    Interesting read

    Just got Vista Home Basic with my Dell E521 deal

    beefed it up to 4 x 512MB DDR2 (dual channel)

    My 1st gen. 512MB iPod Shuffle works with ReadyBoost to my surprise.

    I’ve tried external card readers with SD cards, it doesn’t work

    Gonna try my Kingston 2GB U3 usb drive later too

    Sad to say, I haven’t noticed any significant increase (I allocated 100% of 512MB for ReadyBoost)

    Question though: does having a external USB device/drive plugged in all the time, prevent Vista Sleep mode?

    I can’t quite figure it out yet, my Vista will come back from Sleep mode occasionally if I have my Shuffle plugged in

  210. Steven says:

    Keep in mind not all USB flash drives give the same performance. Readyboost has minimum performance requirements that are checked before the drive is allowed to be used.  Vendors are starting to label readyboost compatible drives. High end drives like SanDisk’s Cruzer Titanium should work fine.

  211. Craig Kowalski says:

    I’m running Vista premium w/1gig internal RAM and a 2gig pny optima pro attache (got a good deal on it $35) that is readyboost compatible.

    QUESTION:  does anyone know if this flash drive will still be as good for readyboost if I just have it plugged into my 4 port usb hub, instead of being directly plugged into a usb slot on my laptop?  For some reason my laptop only has 2 usb ports and I want to maximize the # of ports I can use.

    It shows up in my computer when I have it plugged in via the 4 port hub, I just didn’t know if this was still a good idea.

  212. Craig Kowalski says:

    also, forgot to ask:

    this is a 2gb flash drive yet vista is telling me that it recommends only using 1860mb of it for optimal performance.  Will it make any difference if I just manually increase the amount of storage that this drive will use for readyboost?

    Ready boost disappears after rebooting. I was using 2GB PQI 150x SD card in my Dell latitude D420 laptop SD card slot. I was wondering why sometimes the cache file is there, and sometimes it is gone that I had to rebuild the file.

    I was having the problem again, so I just rebooted several times hoping it would come back, but it didn’t. This time the whole drive disappeared. I found out that my 2GB SD card somehow died on me. I’ve been using my laptop heavily with the SD card inserted for about 3 weeks now. Now I can’t read or even format the SD card now. Tested on several computers/card readers, but looks completely dead. I’m wondering if the ready boost caused the problem on my 2GB SD card.

    Does the 150x speed written on the SD card has anything to do? I know it is suppose to be faster, but I’m thinking, does it use higher frequency which might not be safe for ready boost purpose? I also have a 1GB lexar SD with no speed written on it, and that one also works as ready boost, while one of my kingston 1GB SD with no speed marking doesn’t qualify for ready boost.

    It  seems to me that if you "permanently" put in a memory card or USB memory stick and told Windows XP to put the page file on that drive, it would simulate ReadyBoost.

Vista runs nice – the 32 bit version on a 64 bit processor………that’s crap that they didn’t give you the 64 bit version on the DVD except in Ultimate making you pay more money.

    Anyway the reason for my post is to suggest to Matt Ayers if you get a chance to see him again – make readyboost with 100 mbps network support. Your DSL connection only uses up about 5 – 10 mbps max on your router. Say you have two or three or four computers all connected via lan to a router. Imagine being able to map a network drive and using it for ready boost !! Wait……maybe you can fool windows into thinkin a network drive is a regular drive for ready boost………..I’ll go check……….

    Hey, just wondering if anyone has any clue as to what could be my problem. I have an Alienware m9700. I just bought a 4GB Transcend 150x SD card to hopefully speed up my performance in Vista using the built-in card reader. Well every time I use the card, the computer gets really choppy and CPU Usage goes though the roof (around 90-100% and doesnt go down). As soon as I remove the SD card, the computer goes right back to normal. I have tried removing it and plugging it back in several times with the same results. I even tried plugging in my SD card to an SD to USB adapter and it has the same issues, so I know it isn’t the built-in card reader. Anyone have any idea what I could do? Thanks for any help provided

    Found a way to make a SD card work when Vista 64 bit initially said it was not capable … some earlier posters who had problems with their cards or USB sticks might wanna try this

    I’m using 1 GB Sandisk SD card in internal card reader

    Reformat card from FAT32 to NTFS

    retest card using Readyboot… hey presto it works

    after doing this you can put data back on card and still use Readyboost- but you need to leave Readyboost plenty of space to work eg at least 0.5GB

    If your USB key or SD card or whatever is heavily fragmented or is FAT32 it most likely wont work

    Readyboost doesn’t appear to increase performance at all for me at this point.

    Trying a SanDisk 4GB usb drive, Vista finds it right away and allows use of the full 4 gigs, but performance doesn’t improve.

    I’ve tried it on 3 systems in my home:

    Laptop with Vista Ultimate x64

    2 GB ram

    120 GB hard drive 7200 rpm

    AMD Turion 64 x2 1.8 ghz cpu

    Desktop with Vista Ultimate x86

    3 GB ram

    150 GB SATA hard drive 7200 rpm x 2

    P4 3.4ghz x86 cpu

    Desktop with Vista Ultimate x64

    3 GB ram

    150 GB SATA hard drive 7200 rpm x 2

    P4 3.0ghz x64 cpu

    No noticable performance gains.  Waste of money for the usb drive I bought.

    Hey folks,

    I recently bought a LaCie 320 GB external hdd. When I formatted it to NTFS file system it asked me if I would like it to use it for ReadyBoost. I did, because I have only 1 GB of RAM, but it said several times I couldn’t use it because it didn’t meet the requirements. Then suddently it worked, but my computer doesn’t indicate more RAM.

    The package sais up to 480 Mbit/s transfer speed, but I think this isn’t realistic.

    Hello, all,

    I have a Dell E1505 laptop w/ Vista Home Premium, 1.86G Core 2 Duo processor and 2G RAM.  I installed a Lexar Professional 2G SD card (133x) in my laptop, and it seems to have been accepted by Vista as Readyboost-capable.  The SD card was formatted as NTFS, and Vista asked for 1860M of the 2G SD card capacity, so I gave it what it asked for.

    It’s not raising any problems I can see in the event viewer.  However, I’m not sure I can see any noticible effect.  However, this is a relatively unstressed pc.

    Best wishes,

    Today, I found something that I thought to be rather interesting. Recently I discovered that one of my RAM sticks had gone bad and so I’ve removed it, I had been using a 2GB Cruzer mini flash drive as a readyboost drive previous to removing the RAM and so, having removed 1 of my 2 gb of memory, I decided to test what difference my 2 gb drive made. I put a heavy load on my machine (I began ripping a DVD in each of my dvd drives, a deep system scan with my anti-virus, opened a music file, a movie and began compressing one of my backup drives) and watched how my system handled for a few minutes then ejected the readyboost drive and watched for a difference. I did notice a difference but the interesting thing that I observed occurred when I tried to re-enable readyboost on the flash drive. I put the drive back in, while still running a heavy load, and clicked to check for readyboost capabilities, my machine returned that the drive was not capable of using readyboost (even though it had been using it for weeks).  Rather distraught, I ejected the drive again and found that it still wouldn’t run readyboost. I stopped the programs I was running and tested again, this time the drive passed the readyboost check. I bring this up because several people have posted that their flash drives are not capable of using readyboost, I’ve checked these drives against my cruzer and found that a few of them are actually more capable than my readyboost (judged mainly by their av. time). When testing for readyboost, bring your system down to its idle processes then test things out, you might be surprised,  I know I was.

  273. Kyle says:

    re: Patchariadog  

    I don’t think that you’ll be able to. Readyboost doesn’t work like RAM, although that would be really cool if it did. What readyboost does is provide disk space to page to that reads and writes more quickly than your hard drive.

    Basically, when your computer runs out of memory (not storage mind you) it writes pages of unused instructions to the hard drive in order to free up memory. The hard drive is really bad at reading and writing tiny amounts of non sequential data. However, flash drives are great at this and do so many times faster than the hard drive. This is what readyboost does for you. It enables you to read and write memory pages more quickly than your hard drive. Effectively speeding up your system, but, unfortunately, not actually increasing the capabilities of your system.

This tip was already  well-known before but nothing at least… so why don’t we used flash memory(card or usbkey) to boost the system before using slot memory…i think ram memory is outdate(Ram more expensive than usb key)…with the new cpu core…and later flash drive… "fan of new tech. and research"
