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 single-threaded sequential speeds reaching 553MB/s reads and 511MB/s writes. 4K tests at a queue depth of 32 produced 362MB/s read and 357MB/s write performance.
480GB OCZ Trion 150 SSD CrystalDiskMarkResults
The chart below summarizes 4K random transfer speeds with a command queue depth of 32. The Trion 150 shows excellent results only a little off the pace of the top-rated Samsung 850 EVO.
In the next section, we continue our testing using Iometer to measure input/output performance…
