HD Tach v3
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 Agility EX Series SLC 60GB
In HD Tach testing, the Agility EX produced the fastest write speed of the group by a wide margin, at 203.4 MB/s. It came in second place behind Intel's X25-M Gen 1 drive in read speed. Its clear that the Agility EX is a top performer when raw transfer rates are being measured.
