For whatever reason, I/O Operations Per Second (IOPS) is not showed at all. There are lots of people who said that CrystalDiskMark’s 512K test seems kind of redundant to them. In fact, the results were close to the sequential tests and we feel that the 4K test is the most useful test to run. As we explain before that CrystalDiskMark sequential test is constantly the ones with the highest results. So, how about a low CrystalDiskMark score? Let us discuss it now.

In this section, we are going to explain about other types of CrystalDiskMark test. So, we do not suggest you mess with them too much if you only want a fast idea of your SSD or HDD performance. Also, a file size of 1GB is a nice starting point. Usually, running the tests three times is enough to take an accurate result. Apparently, there are five buttons on the left hand side.Īlso, there are three boxes on the top of the UI which offer you to choose the number of runs, the file size to use for the tests and the drive to run the tests on. Roght now, you will be able to download the latest version. Besides, it is going to display the results in IOPS and MB/s.

It is going to run sequential write and read tests as well as random write and read tests.

HOW TO MEASURE HDD SPEED PERFORMANCE BY USING CRYSTALDISKMARKĬrystalDiskMark offers you to select any drive that you want to do many tests on them to measure achievement for writing and reading.
