Read online that Windows has a built in tool called winsat you can use to test disk performance, where you "winsat -disk drive c" to test your c drive. Is that reliable to use just like that to confirm you're getting the speeds out of a M.2 drive that manufacturers advertise on their website for the drives? Or do you need to throw different switches at the command to truly do a better test?

It's a test gives you some numbers run it and see what it says.

Also look at crystaldiskmark or as_ssd.....both free gives more numbers.

Thanks. Was hoping the built in tool was adequate but wasn't sure how good it worked or if there was a better way to use it.

As is in every other benchmark results wary with amount of data used as test file and also depends on weather you are checking/measuring just a partition and type of partition so no tests will show same results.

crystalsikmark has a portable version...

No need to run the default 5 passes, just run it once...

The top line, "SEQ1M/Q8TM" will give you essentially all the info you need, your best case sequential reads/writes....

(Never even heard of 'winsat')

I believe this used to be part of a system performance rating system Microsoft used in Vista and 7 as a way to give the layman a sort of explanation on how their computer can perform. I suppose it would also help software developers set easy minimum requirements (e.g., "your CPU must have a performance rating of 3.0 or higher")

They probably dropped it because the layman doesn't really care or can interpret its results in a meaningful manner.

As I know, winsat can only test the basic write and read speed of hard drive. And the command seems a little complicated. To protect your hard drive, you had better turn to some professional disk speed check tools like crystalsikmark, AOMEI Partition Assistant Professional...
