Benchmark Results: 4 KB and 512 KB Random Writes

The OCZ Vertex 2 Conspiracy: Lost Space, Lost Speed?

Writing data to the drive is similarly affected by queue depth, though the 34 nm-based Vertex 2 picks up significantly more performance when it’s bombed with concurrent requests.

Contrary to what we saw on the previous page, rerunning the test using 512 KB writes does not seem to help performance.

The fact that the Iometer chart shows a relatively minor IOPS hit using compressible data is promising. But CrystalDiskMark’s results are far less impressive across the board, faced with random data.
