OCZ Vertex 450 Solid State Drive Review
CrystalDiskMark Benchmarks
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.

SandForce-based drives have performed well in CrystalDiskMark’s sequential transfers (including apparently the Vertex 3.20, which also posted a strong write score), and the Vertex 450 didn’t catch them all, but it got a lot closer than the Vertex 4 did. The drive also topped the field in the 512K transfer write test (coming in a close third in the read test), giving the SandForce based drives a run for their money.
The Vertex 450’s impressive write speeds evinced themselves further in the 4K and 4K QD32 tests and complemented those scores with mostly solid read results.
