I found this post about how to use winsat to measure disk performance on Windows. But if i mount a network share on drive letter x winsat disk -drive x returns Unable to open the drive or device.

I tried to run in regular powershell (since winsat must be run as administrator but administrator shell can't see mounted network shares) using runas /user:myadminname "winsat disk -drive x" but after authenticating i get error that the requested operation requires elevation even though myadminname is a admin user.

I thought about using the idea from here but I don't know the side affects for other users on the system and i don't want to remap a already mounted network drive.

Is there a way to use winsat to measure network mounted disk performance?

  • have you tried to run winsat disk -drive MappedDriveLetter on your system against any mapped drive? [1] there is no point in running that test on a drive that is mapped across the network. [2] i can't get that test to run on ANY mapped drive. the result is Error: Failed to properly assess the disk. – Lee_Dailey Dec 01 '20 at 01:02
  • These tools are used to test the full spindle. This is a logical vs physical thing. These tools are for the physical drive only. A mapped drive is not a drive. A mapped share name is not a drive. It's a pointer. If you are using real storage devices in your infrastructure, then you are only getting a slice of that drive, again, not a real drive. Thus tools, like you are using, should fail (on network drives, file shares, etc.,) by design. No network admin, in their right mind, would never allow such scans/tests. – postanote Dec 01 '20 at 22:24

As per the MS Docs. You only have 4 assessment options with this tool:

Using WinSAT

https://docs.microsoft.com/en-us/windows/win32/winsat/using-winsat

Initiating an assessment

After Windows 8.1 you can initiate formal and ad hoc assessments of the computer. A formal assessment assesses the following subcomponents of the computer:

  • CPU
  • Memory
  • Primary disk
  • Video card
