CrystalDiskMark TestsCrystalDiskMark 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. Our tests of the Corsair Nova V128 Solid State Drive were each consistent, and also nearly on-target for the suggested maximum speeds. Sequential tests on the Nova V128 produced a maximum read speed of 247.7 MB/s, while the write speed was 172.3 MB/s. Similarly, the 512K results delivered 181.3 MB/s read and 145.3 MB/s write. Up to this point, read speeds have far exceeded write performance. CrystalDiskMark 4K tests produced 27.11 read and 10.10 write performance..
Compared in the chart illustration below, our sequential read and write performance speeds are organized from highest to lowest based on combined total bandwidth:
The Crucial RealSSD-C300 enjoys a noticeable lead atop of our sequential performance chart, producing 363 MBps in read-from transfers and 226 MBps in write-to requests. Both the Intel X25-E Extreme (261/206 MBps) and the OCZ Vertex-EX Single-Layer Cell SSDs (256/182 MBps), along with the WD SiliconEdge-Blue (246/187 MBps) and OCZ Agility-EX (258/172 MBps) offer the highest read and write bandwidth performance. Following closely behind was Corsair Nova with 248/172, Kingston's SSDNow V+ SNVP325 that produced 237/182 MBps, and the Corsair X256 which scored 255/156. Not far beneath 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. Drive Hardware
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.
