The “4KiB” Q8T8 uses 4K file sizes to test the drive using random (2,5,7,1…) reads and writes, which are more resource intensive than the sequential test. If you’re not sure about the results, the “Seq” Q32T1 tests the sequential (1,2,3,4…) read and write performance of the drive. You can hover over the result to see the IOPS results for the tests. Once you’ve completed the steps, the performance tests will run on the disk for several minutes depending on the drive, and after they have been completed, you’ll see the benchmark result in megabytes/second. If you only want to run a single test, you can click the green button on the left. When using the All option, the tool will run all the available tests, including the sequential reads and writes and three different 4KiB random tests.
Using the third drop-down menu on the right, select the drive (HDD or SSD) that you want to test. (The default selection is more than enough in most cases.) Using the second drop-down menu, select the file size that the app will use to benchmark the drive. (If the default is 5, you can change it to 3, which is enough to get more accurate results.) Using the first drop-down menu on the left, select the number of runs. Search for CrystalDiskMark and select the top result to open the app. To measure a drive reads and writes performance using CrystalDiskMark, close all the running programs, and use these steps:

How to measure hard drive speed performance using CrystalDiskMark
In this guide, you’ll learn the steps to use the CrystalDiskMark to test the performance of your solid-state drive or traditional rotating platter hard drive.
DISKMARK SCORES WINDOWS
With how cheap RAM has gotten nowadays, I recommend this option to anyone looking to improve their I/O performance all around.When you get a new device, or you’re upgrading an existing hard drive (HDD) or solid-state drive (SSD), it’s a good idea to test their performance to ensure the drive is working as advertised.Īlthough you’ll find a bunch of tools out there, on Windows 10, you can also use CrystalDiskMark, which is a known tool that allows you to perform a number of tests to measure the reads and writes speeds of virtually any kind of drive.ĬristalDiskMark can run sequential and random read and write tests, and it’ll display the benchmark results in megabytes/second (MB/s) and Input/Output Operations Per Second (IOPS), which is useful information that you can use to understand the performance of your new drive, or figure out if your old drive is losing performance. Open-world games that stream textures such as Grand Theft Auto, Skyrim, Red Dead Redemption and Minecraft all show much more stable framerates when loading in streamed textures when completely removing a disk I/O bottleneck. This configuration makes a pretty significant difference in performance for things that rely on heavy repetitive usage of your disk. Here is what my RAM performance currently looks like:ĭDR4 4400 C19 kit clocked at 4000 c15-15-15-30 with a Command Rate of 2, 4x8GB configuration (single rank). Since all mundane writes are deferred to my RAM instead of my SSD, the lifespan is improved while also improving performance on repetitive tasks and programs that I access more frequently. To improve my performance and longevity of the drive, I am using a block level cache to let my excess memory cache in place of the drive.
