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 in its benchmark tests, so sequential file transfer speeds appear lower compared to those tested with other tools using uncompressed data. This section concentrates on operational IOPS performance using compressed data. CrystalDiskMark 3.0 reports sequential speeds reaching 501.6 MB/s reads and 354.9 MB/s writes. 512K test results reached 311.6 MB/s read and 334.8 MB/s write performance. 4K tests produced 25.78 read and 45.95 write performance.

Maximum 4KB IOPS performance results at queue depth 32 are reported in the chart below. These values represent the performance levels for several enthusiast-level storage solutions, and illustrates which products offer the best operational performance under load:

In the next section, we continue our testing using Iometer to measure input/output performance...
