Frequently asked questions
Does CrystalDiskMark display drive health or temperature?
No, it focuses solely on performance testing. Health and S.M.A.R.T. monitoring are handled by tools like CrystalDiskInfo.
Why do benchmark results fluctuate between runs?
Background system processes, drive caching mechanisms, and thermal throttling can influence active transfer rates during tests.
Is CrystalDiskMark free for commercial use?
Yes, it is released under the open-source MIT license and can be used freely for personal and commercial purposes.
