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.
Each of our tests with the OWC Mercury Extreme Pro 6G Solid State Drive were consistent, and the best results obtained were used in the chart below. Because this benchmark uses compressed data, sequential file transfer (write) speeds are reported lower than with other tools using uncompressed data. CrystalDiskMark 3.0 reports sequential speeds at 500.7 MB/s read and 253.1 MB/s write. 512K results reached 445.4 MB/s read and 256.0 MB/s write performance.
For this section, we will concentrate on the operational IOPS performance using compressed data. 4K tests produced 31.29 read and 80.06 write performance. 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...
