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.
Using CrystalDiskMark, both the Seagate Barracuda XT ST33000651AS (five-platter) and new Seagate Barracuda ST3000DM001 (three-platter) offered very consistent test results. Again, both hard drives produced very similar test scores. After comparing the results, it appears that the new Seagate Barracuda ST3000DM001 (three-platter) hard drive once again shows a small speed advantage. The read and write speeds were just a few MB/s faster with the new Seagate Barracuda ST3000DM001, delivering 3 MB/s faster reads and writes.
