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 3.0 reported sequential speeds reaching 145.7 MB/s reads and 144.0 MB/s writes on the 4TB Seagate Desktop HDD, closely matching Seagate’s specifications for the 5900 RPM drive. Compared to the 7200 RPM drives from the previous generation, the Seagate Barracuda ST3000DM001 (three-platter) and Seagate Barracuda XT ST33000651AS (five-platter) hard drives both performed slightly faster transfers.
