CrystalDiskMark is a very basic read and write benchmark tool by Crystal Dew World that offers performance speed results using sequential, 512KB random, and 4KB random samples. For our tests, sequential read and write performance was measured using a 1000MB file size, with 50, 100, and 500MB being the other available options. CrystalDiskMark requires that an active partition be set on the drive being tested, and all drives are formatted with NTFS.
Benchmark Reviews uses CrystalDiskMark to confirm manufacturer suggested bandwidth speeds. In addition to our other tests, the sequential read and write benchmarks allow us to determine if the maximum stated speed of any storage product is within reasonable specification. In the chart below illustrated below, our sequential read and write performance speeds are organized from highest to lowest based on total bandwidth.
Enjoying a noticeable lead atop of our sequential performance chart, both the Intel X25-E Extreme (261/206 MBps) and the OCZ Vertex-EX Single-Layer Cell SSD (256/182 MBps) and OCZ Agility-EX (258/172 MBps) offer the highest read and write bandwidth performance. Followed closely behind was the Kingston SSDNow V+ SNVP325 that produced 237/182 MBps, and the Corsair X256 which scored 255/156. Not far behind the top leaders was the OCZ Vertex Turbo, which offered 248/145, which is slightly faster than the standard Vertex SSD performance of 230/138. The OCZ Agility followed closely behind the other Indilinx Barefoot SSDs and shared the same sequential write speed penalty.
Although the remaining drives are all within a respectable range of speed, the high-performance VelociRaptor hard drive still keeps pace with a few SSDs. The WD VelociRaptor offers sequential read and write performance comparable to the Mtron MOBI 3500.
