While it's not top dog on sequential reads, it's still very good. Its write speeds are simply untouchable across all our tests, and its queued 4K random read speeds dominate as well. With each new SSD controller and firmware, we seem to get closer to a drive that can do it all. We'd love to see how the 256GB and 128GB editions hold up on our charts in comparison.
OCZ's Everest 2 controller is clearly paying dividends with the Vertex 4 — this is an excellent drive indeed.
