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 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 Crucial m4 SSD were consistent, and the best results obtained were used in the chart below. Sequential tests on this Marvell solid state drive produced a maximum read speed of 410.0 MB/s while the write speed was 277.0 MB/s, compared to 500.6 and 300.5 MB/s for the OCZ Vertex 3.
CrystalDiskMark 3.0 reported 512K results of 329.9 MB/s read and 276.9 MB/s write performance, which compares to 440.0 MB/s read and 295.6 MB/s write for the SandForce SF-2281 SSD. 4K tests produced 21.68 MB/s read and 68.94 write performance, while the OCZ Vertex 3 produced 33.33 MB/s reads and 80.11 writes.
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:
In the next section, we continue our testing using Iometer to measure input/output performance...
