CrystalDiskMark is a disk benchmark software.

Benchmark Core

CrystalDiskMark 4-6 uses Microsoft DiskSpd (The MIT License). So, the benchmark result is NOT compatible with 3.0.x.

Important Notice

• Benchmark result is NOT compatible with 3.0.x
• “MB/s” means 1,000,000 byte/sec.
• The result depends on Test File Size, Test File Position, Fragmentation, IDE(PATA)/SATA/RAID/SCSI controller and CPU speed etc…
• In a part of SSD, the result depends on test data(random, 0fill).

Unit

• 1GiB = 1024MiB = 1024x1024KiB = 1024x1024x1024B
• 1GB = 1000MB = 1000x1000KB = 1000x1000x1000B
