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, similar to digital audio and video multimedia files. This has an impact on the Phison controller inside the MyDigitalSSD BP4 Slim 7 solid state drive, making sequential file transfer write speeds appear lower in this SSD compared to others that prefer uncompressed data. For this reason, we concentrate on the operational IOPS performance for this section.
CrystalDiskMark 3.0 reports sequential speeds reaching 514.3 MB/s reads and 393.3 MB/s writes. 512K test results reached 319.5 MB/s read and 393.1 MB/s write performance. 4K tests produced 22.42 read and 63.99 write performance. All the results produced by CrystalDiskMark for the MyDigitalSSD BP4 Slim 7 solid state drive trail behind 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...
