Wondering what disk speed test tool is best for your Windows PC? You will find out the best tools to speed test your disk, whether it is SSD or HDD, in this article.

The Hard Drive is as important as other PC components like RAM, GPU, and CPU, as it stores files and deals with read/write functions.

The running of any process, including the OS on a PC, depends on all files stored on the PC, including OPERATING system files, all of which need to be read before they can be used.

So how fast needed files can be read or the other way round, written determines the responsiveness of a PC during boot, during file transfer, when trying to open a program, and the overall performance of a PC

Since your whole system is dependent on the disk read/write speed, you may want to check the maximum read/write speed your disk can render to analyze the disk, compare it with another disk, or for any other reason.

We have tested several disk speed test tools for Windows and picked the ten best ones, which we will be discussing one by one in this article.

But before that, let us look at why you should test disk speed on your Windows PC. So, let’s dive right in.


Why Test Disk Speed on Windows PC?

You’ve probably experienced a sluggish startup on your Windows PC, and while various things could be at fault, slow disk speed is one of the most common causes of this issue.

Hence, you’ll need a disk speed application to test your disk’s current maximum speed, establish whether it’s influencing your PC’s slowness, and fix any issue occurring as a result.

Moreover, disk speed tests play a pivotal role in evaluating the operational efficiency of storage devices; when getting an HDD or SSD for a PC, it is best to test its speed to ensure it will function well enough on the computer—depending on the tasks to be performed with the computer.

Other key reasons to do a disk speed test on a Windows computer are to determine if the storage disc is a bottleneck in the system, causing longer loading times and data retrieval delays, or to compare it to another storage device.

How do I check my disk speed on a Windows computer?

There are a couple of ways you can check disk speed natively on a Windows computer: One is through the Command Prompt, which provides comprehensive details for any chosen drive on your system. The other is via the Task Manager, which displays only the real-time disk speed.

To check disk speed on a Windows computer via Command Prompt:

  1. Press the WINDOWS key + R to open the Run dialog.
  2. Type cmd in the box, and press CTRL + SHIFT + ENTER to open the command prompt as administrator.
  3. On the command prompt window, type winsat disk -drive c and press Enter to run the command. The “c” in the command denotes the drive being tested; for example, if you are testing a drive with a different letter, say drive D, the command will be winsat disk -drive d.

In a few minutes, you should get the tested disk’s read/write speed along with other related results.

To check disk speed on a Windows computer via Task Manager:

  1. Press CTRL + SHIFT + ESC to open Task Manager.
  2. Go to the Performance tab and select the drive to check its read/write speed.
  3. The read/write speed of the drive will be displayed at the bottom of the window; however, this is only the current disk speed on the drive and not the maximum speed.

Using a disk test tool beats these native methods of checking disk speed since it allows you to customize your disk speed test and provides a more complete analysis of the disk speed. If you require a more thorough speed test of your disk, you can use any of the tools mentioned above.


Frequently Asked Questions

What read/write speed is best for my drive?

The answer depends on the type of hard drive you’re using, whether it’s an HDD or an SSD, as well as the hard drive’s specifications. Furthermore, the best read/write speed will vary depending on the intended use of your PC; however, for general processes on a PC, the ideal speed and hard drive should match the following criteria:

HDD: For optimal performance, although not recommended for extremely resource-intensive tasks, consider using an HDD with a read/write speed ranging from 100Mb/s to 160Mb/s. Some HDDs can even reach speeds of up to 250Mb/s.

SSD: For peak performance, particularly for gaming and tasks that demand moderate read/write speeds, opt for an SSD with a read/write speed range of 250Mb/s to 500Mb/s. However, keep in mind that some SSDs are capable of achieving read/write speeds as high as 2500Mb/s or even greater.

If you have less than the above-mentioned speeds, you may experience problems with some computer functions.

Is there a way to test SSD speed?

Yes, you can use tools like DiskMark, NovaBench, or CrystalDiskMark to test the speed of your SSD. These tools load a specified quantity of test data into your hard drive by writing the data to the storage device and then reading the data from the storage, thereby generating a scenario to read/write and determining the speed required for each operation.

During the test, the process of writing and reading data is done multiple times to get an accurate read/write speed for you.

What is the best disk speed test tool?

Each of the disk testing tools mentioned in this article has been tested and has proven to be among the best available.

Nonetheless, CrystalDiskMark distinguishes itself within this selection as a specialized tool that offers a user-friendly approach to assess disk read/write speeds and permits customization of test parameter.

Wrap Up

Periodically conducting disk speed tests is advisable to keep track of your disk’s performance, pinpoint any potential hardware bottlenecks in your computer, or compare speeds across various disks.

This article covers the top tools, offering both paid and free options, giving you the flexibility to select the one that suits your needs.

However, you should avoid performing this test too frequently as it may create wear and tear on your disk.
