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 SSD produced a maximum read speed of 383.6 MB/s, while the write speed was 199.0 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 353.2 MB/s read and 197.4 MB/s write performance. 4K tests produced 23.99 read and 79.52 write performance. 4KB queue depth 32 IOPS is one area where SandForce-driven SSDs truly excel, and performance for the 120GB OCZ RevoDrive leads the other SandForce SSDs with 233.4 MBps read and 192.6 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 to the 231/150 MBps maximum 4KB queue depth 32 IOPS two separate SandForce SF-1200 SSDs in RAID-0 produced, the OCZ RevoDrive matches read performance and heavily outperforms in write operations.
