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 541.3MB/s reads and 493.1 MB/s writes. 512K test results reached 433.6MB/s read and 385.4 MB/s write performance. 4K tests produced 33.85MB/s read and 92.21MB/s write performance. As we’re starting to see, the read speeds of this drive are very good, at or near the best we’ve seen in these benchmarks so far, while writes are a little off the pace.

The chart below summarizes 4K random transfer speeds with a command queue depth of 32. The BP5e returns solid mid-pack results for reads, but is somewhat off the pace in writes.
