We begin testing using Anvil's Storage Utility. The idea is to start with fresh out-of-the-box drives and a 4 GB test file.
Plextor's M5 Pro comes out on top in the read benchmark. Specifically, it does well in 4 KiB transfers, though it falls behind the Vertex 4's write results at queue depths of four and 16. Overall, ASU puts the M5 Pro just behind OCZ's Vertex 4, which was recently augmented with new firmware (OCZ Vertex 4 128 GB: Revisiting Write Performance With Firmware 1.5). But, it still manages to outpace the other competition.
