If you need help with how to run the disk performance test on Windows, I'm here to help. In this article, I'll try to clear up any confusion about disk performance and show you two amazing methods for running disk performance tests on Windows.

But before that, let's first discuss disk performance and how it can affect your system and the overall experience of your PC.

What Is Disk Performance

You may not be strange to the phrase "speed up computer performance." However, do you know what disk performance means? A hard disk contains your computer's software applications and data. Plus, hard drives are much slower than RAM, meaning your PC will operate much more slowly when accessing data from it. Additionally, the overall performance of your drive is assessed by the following:

  • Command overhead: The time the disk controller takes to process I/O requests is the command overhead.
  • Seek time: The seek time calculates how long the actuator arm's head assembly takes to move to the track on the disk where the data is to be read or written. 
  • Rotational latency: This is the time taken for the disk to rotate and bring the necessary disk sector under the read-write head. 
  • Data transfer time: The data transfer rate is the speed at which data is moved from the disk surface to the drive's controller and from there to the host system.

It matters much that you run a disk performance test or SSD performance test on Windows regularly. The next part will teach you how to test the disk performance.

Step 1. Click the "Start" and type "cmd" in the search box. Or you can also use the "Windows + R" keys to get the "Run" box and type "cmd" to get the terminal.

Step 2. Now right-click on the "cmd" and select "Run as administrator."

Step 3. Type "winsat disk -drive c" in the command prompt window and press "Enter." Remember to replace the "c" with the target drive letter.

Disk Performance Test on Windows FAQs 

The guide covers everything you need to know about disk performance tests on Windows. However, you can check the FAQs below if you still have queries.

1. How do I check my hard drive performance Windows 10?

Download the EaseUS Partition Master tool to check the performance of your disk without any risks of losing data. You can also choose to use the Windows Command Prompt. Here's how to test your disk using CMD.

Step 1. Run the Command Prompt as an administrator.

Step 2. Type "winsat disc -drive d" and hit the "Enter" key. The letter "d" is the drive letter you want to test.

All of the disk performance statistics will be visible on your screen.

2. Why is my PC so slow and disk at 100%?

100% disc usage may cause your computer to lag and offer slow performance in everything you do. This occurs when numerous background and foreground applications run simultaneously on your system. As a temporary fix, you can try pausing background programs and rebooting to clear everything from memory.

3. Can CHKDSK improve performance?

You can use CHKDSK to check your hard disk for damaged files, assist in PC repair, and do deep clean-up to keep your drive in good working order. Although CHKDSK may not directly increase the speed of your PC, it can help free up storage space, which frequently has a similar impact.
