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 LE - 100GB MLC SSD


Intel X-25M G2 - 160GB MLC SSD

 
Micron RealSSD C300 256GB (SATA 3G)
 
OCZ Vertex 120GB


The OCZ Vertex LE offered up great read throughput and best of class write throughput, even competing with Micron's new C300 SSD.  To keep the playing field level, the Micron numbers here we taken with a 3Gbps SATA setup.  If you'd like to see the 6Gbps numbers you can take a look here.  The new Vertex LE drive excels in small block random write performance and handily outpaced the Intel X25M in 4K transfers with a queue depth of 32. Micron's new SSD clearly offers the best read throughput in this test, while the OCZ Vertex LE offers the best overall write performance, save perhaps for large sequential transfers.
