If you are looking for a way to check SSD speed using Command Prompt, you come to the right place. In this post, MiniTool Partition Wizard provides a step-by-step guide to help you do this.

Why Need to Check SSD Speed?

Knowing the speed of your SSD can help you master the health and performance of your computer. SSD speed mainly includes write speed and read speed. The write speeds refer to the speed of recording external data into the storage device, while the read speeds refer to the speed of extracting data from the storage device.

So, if you want better system performance and responsiveness, you must regularly test SSD read/write speed and performance.

How to Check SSD Speed Using Command Prompt?

Command Prompt is a command line interpreter application available on the Windows operating system. You can use it without downloading any applications on your PC. If you want to use it to test SSD speed, you can follow these steps:

Step 1. Press the Windows and S keys at the same time to open the search window. Then type “cmd” in the search box.

Step 2. Right-click Command Prompt under Best Match, and then select Run as administrator from the menu.

Step 3. Next, type the command “winsat disk -drive c” and press Enter to test SSD read/write speed. (You can also switch “c” with your drive letter.)

If you just want to know the random write speed, you can run the command "winsat disk -ran -write -drive -c". If you just want to know the random read speed, you can run the command "winsat disk -ran -read -drive c".

Step 4. Once done, you can see your SSD speed clearly.

Other Ways to Test SSD Speed

In addition to doing the SSD speed test using Command Prompt, you can also use the other two methods to do the SSD speed test. They are:

1. Use Task Manager to Check SSD Speed

You can also check the SSD speed in the Task Manager. To do that, you just need to press ESC, Shift, and Ctrl at the same time to open the Task Manager window, go to the Performance tab, and then select SSD Disk from the left panel. After that, you can see the SSD’s read and write speeds clearly.
