PCMark 7 Storage Benchmarks
We really like PCMark 7's Secondary Storage benchmark module for its pseudo real-world application measurement approach to testing. PCMark 7 offers a trace-based measurement of system response times under various scripted workloads of traditional client / desktop system operation. From simple application start-up performance, to data streaming from a drive in a game engine, and video editing with Windows Movie Maker, we feel more comfortable that these tests reasonably illustrate the performance profile of SSDs in an end-user / consumer PC usage model, more so than a purely synthetic transfer test.

There is only about a 7.5% delta separating all of the drives we tested in PCMark7. But the best performance overall comes by way of the two SandForce-based drives, followed closely behind by the Samsung drive and the new OCZ Vertex 4s.
If we tunnel deeper into the individual PCMark7 storage benchmark tests, we can see how the overall score is derived. the Vertex 4 drives trade victories with the Samsung SSD 830 series drive here, with the SandForce-based OCZ and Corsair drives leading by a tiny amount in the majority of the tests.
