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. 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 single-threaded sequential speeds reaching 1589MB/s reads and 1468MB/s writes. 4K tests at a queue depth of 32 produced 762MB/s read and 571MB/s write performance.

The chart below summarizes 4K random transfer speeds with a command queue depth of 32. In this one section of the CrystalDiskmark test, the 960 PRO falls behind its predecessor in read speeds, although it overtakes it in write speeds. Still, note the staggering sequential read and write speeds in the CrystalDiskMark results above.
In the next section, we continue our testing using Iometer to measure input/output performance…
