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, and since the OCZ/Indilinx Barefoot 3 platform is not dramatically effected by the compressed data used in this benchmark sequential file transfer speeds appear higher than SSDs that prefer uncompressed data. For this reason, we concentrate on the operational IOPS performance for this section.
CrystalDiskMark 3.0 reports sequential speeds reaching 522.0 MB/s reads and 510.8 MB/s writes. 512K test results reached 422.9 MB/s read and 499.5 MB/s write performance. 4K tests produced 27.37 read and 96.72 write performance. All the results produced by CrystalDiskMark for the OCZ Vector SSD are significantly better than previously tested 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...
