CrystalDiskMark

Measures sequential and random read, write, and mixed performance of hard drives, SSDs, and NVMe storage devices on Windows systems

It takes care to curate a safe software space. Help us do more.

&

+
Sequential Benchmarking
Measures large contiguous read and write transfer speed to show peak throughput of a drive.
+
Random 4K/512K Testing
Measures small random read and write performance, including a queue-depth-32 4K test, to reveal responsiveness under scattered I/O.
+
Selectable Test Data
Lets the tester pick random, 0-fill, or 1-fill data patterns to expose drives that shortcut compressible test data.
+
Preset Test Profiles
Offers Peak, Real World, and Demo profiles preconfigured for different benchmarking scenarios.
+
Portable Operation
Runs from a ZIP archive with no installation, letting a tester carry it on removable media.
+
Command-Line Automation
Accepts command-line parameters so benchmark runs can be scripted and repeated unattended.
+
Multi-Language Interface
Displays menus and results in dozens of languages for use across different locales.
+
Theme Selection
Switches between visual skins, including character-themed Aoi and Shizuku editions, without changing the benchmark engine.
-
No Continuous Monitoring
Produces one-off benchmark snapshots rather than tracking drive performance in the background over time.

Notes

  • AmorphousDiskMark is a separately developed macOS-only clone with a similar interface, made with the CrystalDiskMark author’s permission — it is not an official CrystalDiskMark release.
  • CrystalDiskMark also ships in themed variants (Standard, Aoi, Shizuku) that share the same benchmarking engine and differ only in UI skin.
