CrystalDiskMark is a new synthetic test we've started looking at that tests both sequential as well as random small and large file transfers. It does a nice job of providing a quick look at best and worst case scenarios with SSD performance, best case being large sequential transfers and worse case being small, random 4K transfers.
Micron RealSSD C300 (SATA 6G)
Micron RealSSD C300 (SATA 3G)
Intel X25-M Gen 2 160GB
OCZ Vertex 120GB
These are perhaps the most impressive results for the Micron C300 in this article. In terms of sequential read and write performance, the story doesn't change much from the previous benchmarks--the drive is fast on SATA II and really opens up on SATA III. If you look closely at the 4K transfer tests though, you'll see what's so impressive. The C300 is not only faster than even the Intel drive with regard to 4K writes (and reads), but as the queue depth is increased it simply blows everything else out of the water.
