HD Tach v3 Performance

Simpli Software's HD Tach is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives, flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device being tested."

OCZ Vertex  2 Pro 100GB

Intel 34nm X25-M Gen 2 160GB

Intel X25-M Gen 1 80GB

OCZ Verex Series 120GB

In HD Tach testing, the OCZ Vertex 2 Pro once again dominated the rest of the pack in terms of write performance. It was actually quite impressive to see just how linear and flat the performance of the drive is with respect to its read throughput, which is basically identical.  At least within the scope of our HD Tach scores, the OCZ Vertex 2 Pro shows that write performance limitations of SSDs can be addressed successfully with the a sophisticated Flash controller engine and an intelligent algorithm.  In terms of read requests, the Sandforce 1500-infused OCZ Vertex 2 Pro puts up best-of-class throughput competitive with Intel's latest gen 2 offering.
