Verdict:ĬrystalDiskMark is a very simple benchmarking tool, with only basic reports, but an accurate engine (Microsoft's DiskSpd) and general ease of use earn the program a thumbs up from us. Most of our users download and install our apps through the Platform's built-in app store and then keep them updated using the platform's built in updater. Your results may be saved to disk or copied to the clipboard for reuse elsewhere. Once the benchmark is complete, you're presented with read and write speeds in MB/s for each of the four tests (or just the one you selected). At a minimum you can just choose the drive you'd like to assess (standard hard drives are supported, including network drives, but USB and optical drives are not), hit "All!", and wait for the tests to run.

If you know what you're doing, you can tweak the queue and thread numbers, change the test data, interval times, the test data file size, and more.īut even if you're clueless about most of that, CrystalDiskMark is still very usable. The program supports four tests: "Seq Q32T1" (sequential read/ write with multiple threads and queues), "4K Q32T1" (random read/ write with multiple threads and queues), "Seq" (sequential read/ write with a single queue and thread) and "4K" (random read/ write with a single queue and thread). CrystalDiskMark is a portable tool which measures read and write performance for your chosen storage device.
