CrystalDiskMark is benchmark software that measures the transfer speed of media data storage drive such as HD, SSD, USB memory, SD card and NAS.

  • Important Notice

Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. Therefore, this project needs more development funds. As to current status, this project is extremely short of funds and is in desperate need of your donations.

If you want to contribute to supporting the continuance of this project, please make donations by Paypal. Please make the amount of each contribution $10 USD or more (in JPYen, 1000Yen or more) if possible. Your contributions will be deeply appreciated.

The use can go from serious to relatively easy, Lightweight and after using it in literaly hundreds of machines, havent had a single problem. A toolkit any IT pro should have, and the casual user may not find difficulty to extract valuable information about his disk performance.
None that isnt worth mentioning.
