CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. 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.
The OCZ Vector also performed very well in the CrystalDiskMark benchmark. Here, the Vector was the fastest drive in the large sequential write transfer tests and among the best in the 4K transfer tests. Notice the strong performance in the 4K QD32 test where the Vector outpaced all comers, save for the Vertex 4.
