Have you ever wondered how fast your hard drive is working? If so, there is a way to find out the speed of your hard drive using Windows 10. Testing the speed of your hard drive can provide useful information about its performance and overall health. In this article, we will demonstrate how to assess hard drive speed on Windows 10. 

How to Test Hard Drive Speed on Windows 10?

Here is a step-by-step guide on testing hard drive speed in Windows 10.

Step 1: Open the Command Prompt 

The first step is to open the command prompt. To do this, type in the Windows search bar Command Prompt and run as admin. 

This will open a black window with white text, allowing you to input commands.

Step 2: Run the “winsat disk” Command 

Once the command prompt is open, type in the following command to test your hard drive performance and speed: “winsat disk”. This will run a diagnostic on your hard drive and give you a detailed analysis of its health and performance.

Step 3: Interpret the Results 

The results of the “winsat disk” command will vary depending on your hard drive, but you should see something like this: 

“Disk Score (Current): 9.9 

Read Speed: 296 MB/sec 

Write Speed: 232 MB/sec 

Average Seek Time: 0.820 ms”

The Disk Score is the most important metric here, as it gives you an overall indication of your hard drive’s performance. The higher this figure, the more efficient your hard drive’s performance.

The Read and Write Speeds give you an idea of how fast data can be transferred to and from your hard drive. A higher value is better here as it means that data will transfer faster.

The Average Seek Time signifies the duration your hard drive requires to locate a particular piece of data. Again, a lower number is better here, as it indicates a faster seek time. 

Step 4: Troubleshoot if Necessary 

If your hard drive’s performance is lower than you expected, there are a few things you can do to improve it. One of the most effective methods to enhance your computer’s speed is to upgrade your hard drive. An SSD (Solid State Drive) is much faster than a traditional HDD and will give your system a noticeable boost in speed. 

Another approach to free up space on your hard drive is by uninstalling unnecessary programs and deleting any unused files. This will help to improve performance, as there’s less data for your hard drive to search through. 

Finally, you can try running disk defragmentation software such as Auslogics Disk Defragmenter or Piriform Defraggler. This will reorganize the data on your hard drive, making it easier for your hard drive to access it and improving performance. 

The Importance of Testing Hard Drive Speed 

Why does testing Hard Drive Speed matter, you ask? Consider your computer to be like a busy highway. The hard drive is the road itself, and the data are the vehicles. The faster and smoother the road, the better the traffic flow. Similarly, a hard drive with greater speed ensures efficient data transfer, resulting in improved overall computer performance. 

Testing the speed of your hard drive on Windows 10 can unveil any underlying issues that might be slowing down your system. This helps in identifying whether the slow performance is due to the hard drive or other components of the system. More importantly, it allows you to take timely corrective measures such as disk cleanup, defragmentation, or even an upgrade to an SSD.

Moreover, regular speed tests can also aid in preventive maintenance, giving you a heads-up before your hard drive fails completely. This way, you can back up your valuable data before it’s too late.

So, testing hard drive speed on your Windows 10 system is not just about ensuring optimal performance, it’s also about safeguarding your digital assets and ensuring a seamless computing experience. After all, who needs a road full of potholes when you can pave the way for a smooth journey?


Testing your hard drive speed is a great way to ensure that your computer is running at optimal speed. It’s easy to do and can provide valuable information as to why your computer might be running slower than it should be. By understanding your hard drive’s performance metrics, you can make adjustments and optimizations to get the most out of your system. With a little bit of work, you can have your computer running at peak efficiency in no time!
