How to Test Disk Performance with CrystalDiskMark

We would like to get a high performance from the discs we are using. What offers high performance is the read and write speeds of these discs. While the internal HDD and SSD performance of your computer directly affect the computer performance; The read and write performance of external memories and USB sticks indicates the loss of time when you use these memories.

One of the most robust third-party software you can use to measure disk performance is CrystalDiskMark. CrystalDiskMark is one of the most frequently used software for disk performance. It is the first choice of many users due to its easy working principles and small footprint. Let’s take a closer look at the answers to questions about what CrystalDiskMark is, how to use it, and how to measure disk performance.

What is CrystalDiskMark?

CrystalDiskMark is a software developed for disk comparison process on computers with Windows operating system. Working on one-to-one principles with the Microsoft Diskspd tool, CrystalDiskMark has been performing sequential and random reads since 2007, revealing the read and write performance of disks.

How to test disk performance with CrystalDiskMark?

  • Step #1: Download CrystalDiskMark software from here.
  • Step #2: Complete my council.
  • Step #3: Start the software.
  • Step #4: From the first menu, select the number of runs as 3.
  • Step #5: Leave the benchmark size as default in the second menu.
  • Step #6: Select the disk you want to test from the third menu.
  • Step #7: Start the test by clicking the All button.
  • Step #8: The testing process will be completed after a period of time that varies depending on the disk size.
  • Step #9: The process is complete.

To test disk performance with CrystalDiskMark, simply follow the above steps. For a basic testing process, you can leave the options in the menus as in the steps. If you want to run different tests on disks, you can choose a different run count and benchmark size.

How to use CrystalDiskMark?

We explained how to do a basic disk performance test with CrystalDiskMark. It is a basic test that we describe because when you click the All button, the software; It starts doing all the tests it can, including sequential read-write and three different 4KiB random tests. Therefore, it may take a little longer, but all tests will be applied.

CrystalDiskMark results are displayed in megabytes per second (MB/s) and input output per second (IOPS). If you bought a new disc, you can see if it matches the manufacturer’s information, or you can find out whether a disc you have been using for a long time has expired.

The Seq Q32T1 in CrystalDiskMark results shows the sequential read-write results, while the 4KiB Q8T8 shows the random read-write results. The 4KiB Q8T8 uses the 4K document size to test disk performance. It is best to do all the tests with the All button and see all possible results and evaluate accordingly.

How to evaluate CrystalDiskMark results?

How you evaluate the CrystalDiskMark results depends entirely on the disc you use. Because the read and write speeds of an HDD and an SSD or an external memory and USB memory are never exactly the same. For this reason, test results should be examined on a device-specific basis.

When you buy a new disc, you can test it with CrystalDiskMark and check whether it shows the performance that the manufacturer claims. If you have a disk that you have been using for a long time, you can test it with CrystalDiskMark to see if it is as strong as before and decide to buy a new disk if necessary.

Is it safe to test disk performance with CrystalDiskMark?

Although CrystalDiskMark is a software that has been used for a long time, there has been no random comment that it causes disk damage. But there is a situation, this test takes the life of the disc. In other words, if you measure disk performance with CrystalDiskMark whenever you think about it, you will have wasted disk life.

We answered the question of how to test disk performance with CrystalDiskMark and talked about some details you need to know about this software. Even if CrystalDiskMark is not a software you can use all the time, it is extremely valuable to know how to use it when necessary.
