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."

In HD Tach testing, the OCZ Vertex LE showed anything but variance in its graph plot across the volume.  The drive chalked up slightly better write performance at 234MB/sec on average versus its 222MB/sec for reads.  Again, the Vertex LE drops in just ahead of the Micron drive in write performance and just behind it for read bandwidth.
