CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers.
CrystalDiskMark shows the OCZ RevoDrive Hybrid competing well with the Vertex 3 MaxIOPS drive and clearly dominating the Z68-system featuring Intel Smart Response Technology and the Momentus XT. The RevoDrive Hybrid wasn't able to come close to its theoretical peak performance in this benchmark, however.
Performance didn't vary much from run to run in CrystalDiskMark either. It appears the Dataplex caching algorithms are able to react very quickly to certain access patters, like those used in this benchmark.
