Benchmark Results



ATTO disk benchmark allows us to run a synthetic test on the various drives which are being reviewed today, letting us see the peak speed achieved on each model.

In this review we are comparing the Vertex 4 drives to a selection of drives based on alternate controllers, the Marvell based Corsair Performance Pro, OCZ’s Sandforce based Vertex 3, and Samsung’s 830 Series. This allows us to see how the various architectures compare and in the first test, which mainly focuses on speed, we see a reasonable spread of results.

In this test we see the Vertex 4 offering speeds in excess of 500MB/s for read operations, a level above the Octane drive we reviewed a few months back. The Marvell drive sits a little below the Vertex 4 with Samsung and Sandforce peaking slightly higher. Write operations show the 512GB Vertex 4 to be the second fastest drive, behind OCZ’s own Vertex 3 480GB and the difference in performance between the two Vertex 4 models is apparent with the 256GB sitting at 376MB/s.
