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 520.3 MB/s reads and 500.0 MB/s writes. 512K test results reached 456.9 MB/s read and 381.6 MB/s write performance. 4K tests produced 34.72 read and 68.24 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:

    I would have liked to have seen a seperate IOP’s test that shows the read and write iops and if they were anywhere near the stated values for the SSD , combined values of 50/50 is not a normal scenario for everyday use it would be more like 80R/20W …..

    Other than that very nice review Olin thank you
