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 ICH10 controller set to 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.

Each of our tests with the 3TB Seagate Barracuda XT hard drive were consistent, but only the best test result speeds were charted below. Sequential tests on this mechanical storage device produced a maximum read speed of 165 MB/s, while the write speed was also 165 MB/s. CrystalDiskMark 3.0 reported 512K results of 59.54 MB/s read and 86.76 MB/s write performance, which actually outperforms a few of the latest SSDs. 4K tests produced only 0.719 read and 1.664 write performance. 4KB queue depth 32 IOPS is one area where SSDs truly excel, and HDDs do not.

Displayed in the chart below, the maximum 4KB queue depth 32 IOPS performance results for several enthusiast-level storage products illustrate which products offer the best operation under load:
