The easiest method to test speed of hard drive

When you want to check the read and write speed of your hard drive, no matter HDD or SSD, the easiest way is not searching and downloading software. The fastest method is using the built in command of Windows OS (there should be a lot in Mac OS and Linux): winsat.

First, run the CMD command as administrator by typing it into the command box (click the start button on the left down corner of your desktop, or press Windows logo key + R), then, e.g. if you would like to check C drive, type the command as follows,

winsat disk -drive c

And then hit the “enter” key to run the command. Wait for a moment, you will get the result of the drive just tested.




How is the performance of your drive? Welcome to post it in the comment area. Mine is as follows:
