SSD is loved by many users because of its read and write speed far exceeding HDD. When we buy a new SSD hard drive or a new computer, we need to test its read and write speed to see if it is consistent with the merchant's claim. There are many disk analysis and testing tools like this, and they are also very functional. But if you just want to test the disk's read and write speed, you can use the WINSAT command of the Windows system without installing other third-party tools. In this post, I will briefly introduce how to use WINSAT to test the read and write speed of SSD.
WINSAT is the abbreviation of Windows System Assessment Tool. It is a module of Microsoft Windows operation systems that is available in the Control Panel under Performance Information and Tools. It measures various performance characteristics and capabilities of the hardware it is running on and reports them as a Windows Experience Index (WEI) score. – Quote from Wikipedia.com
Since Microsoft deleted the graphical user interface for WINSAT in win8 and onwards, we can only run the WINSAT command in Command Prompt or PowerShell.
Hold the Windows logo key + s key on the keyboard to open the Search window. Type cmd in the search box, and click Run as administrator.
Type the following command in the Command Prompt and hit the Enter key. For example, check drive C.
winsat disk -drive c
Let's scroll to the bottom of the report, and focus on the following 3 items.
From the report, we can know that the reading speed of my C drive is 1839.53 MB/s, and the writing speed is 3108.04 MB/s, which is basically consistent with the speed claimed by the manufacturer.
WINSAT can not only test disk performance, but also CPU, memory, and other functions. For details, please refer to the documentation about WINSAT on the Microsoft, or use the command winsat /help
