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 486.8 MB/s reads and 326.2 MB/s writes. 512K test results reached 419.6 MB/s read and 322.2 MB/s write performance. 4K tests produced 32.01 read and 92.87 write performance. All CrystalDiskMark results produced by this 240GB OCZ Vertex 3.20 SSD were roughly equal to the previous-generation Vertex 3 series, yet trailed behind some recently released solid state drive products.
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...
