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.
Our tests of the ADATA S599 SandForce SF-1200 Solid State Drive were each consistent, but also far below the suggested speeds (a common problem with the CDM tool). Sequential tests on the S599 produced a maximum read speed of 210.5 MB/s, while the write speed was only 90.26 MB/s. Similarly, the 512K results showed a similar trend: 198.4 MB/s read, and only 86.10 MB/s write. Up to this point, read speeds have far exceeded write performance, at least until our 4K tests. CrystalDiskMark 4K tests produced only 16.84 read and 60.56 write performance. Finally, the 4KB QD32 results measured 115.4 MB/s read and 82.18 MB/s write. These results have been charted below:
In the next section, I share my final thoughts on the struggle between SSD and HDD technology before delivering my conclusion and final product rating.
