PCMark 7 Storage Benchmarks
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.
