I'm doing some work with Microsoft's relatively new DiskSpd.exe.
You can find this tool and documentation at the following link.
Diskspd, a Robust Storage Testing Tool, Now Publically Available
This will be one of my shortest blog posts ever :-)
Just wanted to leave a note that, if you use the -c option to create a test file and IFI (instant file initialization) is not available for the account running DiskSpd, you'll see this message:
Error adjusting token privileges for SeManageVolumePrivilege (error code: 1300)
WARNING: Could not set privileges for setting valid file size; will use a slower method of preparing the file
I like messages that make the situation clear :-)
