SQLIO Disk Subsystem Benchmark Tool is being retired

We are retiring the “SQLIO Disk Subsystem Benchmark Tool” and the download will no longer be available starting today. The download page will still be online for a while since this tool is very popular in various search engines. SQLIO download page has been updated to redirect to the dskspd tool. Microsoft recommends using dskspd tool for storage testing for SQL Server.
