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 ICH10 controller set to 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.
Sequential tests on the OCZ RevoDrive X2 SSD produced a maximum read speed of 680.9 MB/s, while the write speed was 279.0 MB/s. The sequential file transfer speeds have traditionally been low with this benchmark tool because of uncompressed data, especially in regard to SandForce controllers, which is why we concentrate on the operational IOPS performance for this section.
CrystalDiskMark 3.0 reported 512K results of 580.3 MB/s read and 279.1 MB/s write performance. 4K tests produced 28.32 read and 77.56 write performance. 4KB queue depth 32 IOPS is one area where SandForce-driven SSDs truly excel, and performance for the 240GB OCZ RevoDrive X2 leads the other SandForce SSDs with 291.2 MBps read and 258.1 MBps write.
Displayed in the chart below, the maximum 4KB queue depth 32 IOPS performance results for several enthusiast-level storage products illustrate which products offer the best operation under load:
Compared with two separate SandForce SF-1200 SSDs in RAID-0 that produce 231/150 MBps maximum IOPS at 4KB queue depth 32, both the standard OCZ RevoDrive and RevoDrive X2 exceed read performance and heavily outperforms in write operations.
