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.
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, the OCZ Vertex EX Single-Layer Cell SSD offers the highest bandwidth. Followed closely behind by the OCZ Summit MLC SSD with 128MB cache buffer. Not far behind the top leaders is the OCZ Apex, and it's twin cousin the G.Skill Titan. Next comes the Patriot Torqx, followed by the Super Talent UltraDrive ME which has slightly better performance than the OCZ Vertex MLC SSD. The OCZ Agility followed closely behind the Vertex SSD and shared the same sequential write speed penalty. Although the remaining drives are much older models, the SLC construction keeps the OCZSSD2, Mtron MOBI 3500, and MOBI 3000 all within respectable range.
Even though the high-performance VelociRaptor hard drive is made to look low-end by the results charted below, it's actually very encouraging to see that a hard disk can still keep pace with a few SSDs. The WD VelociRaptor offers sequential read and write performance comparable to the Mtron MOBI 3500 and the first-generation OCZ SLC SSD.
