OCZ Vertex 450 Solid State Drive Review

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.

CrystalDiskMark Benchmarks Synthetic File Transfer Tests

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.
