CrystalDiskMark 3.0 Tests

CrystalDiskMark 3.0 is a file transfer and operational bandwidth benchmark tool from Crystal Dew World that offers performance transfer speed results using sequential, 512KB random, and 4KB random samples. For our test results chart below, the 4KB 32-Queue Depth read and write performance was measured using a 1000MB space. CrystalDiskMark requires that an active partition be set on the drive being tested, and all drives are formatted with NTFS on the Intel P67 chipset configured to use AHCI-mode. Benchmark Reviews uses CrystalDiskMark to illustrate operational IOPS performance with multiple threads. In addition to our other tests, this benchmark allows us to determine operational bandwidth under heavy load.

CrystalDiskMark uses compressed data, so sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance in this section.

CrystalDiskMark 3.0 reports sequential speeds reaching 550.9 MB/s reads and 524.7 MB/s writes, which slightly trailed the 860 EVO. 512K test results reached 479.8 MB/s read and 519.9 MB/s write performance, surpassing the 860 EVO. 4K tests produced 50.29 read and 141.0 write performance, for a substantial read speed improvement over 860 EVO. The CrystalDiskMark results for this 512GB Samsung 860 PRO placed performance near the top of all results collected for SATA-based solid state drives.
