CrystalDiskMark Performance

CrystalDiskMark is a new synthetic benchmark 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 regard to SSD performance, best case being large sequential transfers and worse case being small, random 4K transfers.

OCZ Vertex 2 Pro - 100GB MLC SSD


Intel X-25M G2 - 160GB MLC SSD

 
Intel X-25M G1 - 80GB MLC SSD
 
OCZ Vertex 120GB MLC SSD


The OCZ Vertex 2 Pro punched out the fastest overall results in the CrystalDiskMark test suite, with a much more balanced read/write performance profile.  Though sequential read speeds were a tad slower than the Intel X25-M series drives and OCZ's own legacy Vertex series, if you look at 512K random reads, the Vertex 2 Pro offered better results versus even Intel's Gen 2 SSD.  From a write performance point of view, the two OCZ Vertex drives offer up to 2x the write bandwidth of the Intel SSDs, with the Vertex 2 Pro offering great small transfer random write performance of 70+MB/s.
