CrystalDiskMark
CrystalDiskMark is Windows software for benchmarking disk and storage performance.
What CrystalDiskMark is
CrystalDiskMark is Windows software for benchmarking disk and storage performance. It measures sequential and random read, write, and mixed performance, with custom test profiles and Peak, Real World, and Demo modes. Results can be exported as UTF-16LE text with a BOM, PNG, JPEG, or BMP. The download page lists Standard, Aoi, and Shizuku editions; Standard is offered as an installer, ZIP, and source code download. Listed operating systems extend from Windows XP through Windows 11 and include Windows Server versions through 2025, across x86, x64, and ARM64, though the installer and x64 version exclude XP and Server 2003. SMART monitoring and temperature alerts are also listed. CrystalDiskMark has a free desktop edition, while a separate Microsoft Store edition costs 9.99 USD once. The maker cautions that benchmarking may shorten SSD or USB memory life, and results are not compatible between different major versions. Results can also vary with test file size and position, fragmentation, controller, CPU speed, and sometimes the test data pattern.
