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 537.5MB/s reads and 481.6 MB/s writes. Performance is strong through most of the other parts of this benchmark, although they start to lag a bit, especially in writes, when the utility queues up a bunch of 4K writes.
240GB Premier SP550 SSD CrystalDiskMarkResults
The chart below summarizes 4K random transfer speeds with a command queue depth of 32. The ADATA Premier SP550 does a bit better than mid-pack on reads, but falls rather far behind on writes with its 249.1MB/s score.
In the next section, we continue our testing using Iometer to measure input/output performance…
