HDTach Benchmark

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."

Our HDTach results confirm the previous benchmarks we've run. With an average read speed of 111MB/s, the Caviar Green 3TB was able to keep up with the rest of the comparison group. In comparison, the Barracuda XT was only 5% faster. Unfortunately, read performance remains a weak point, reaching only 31MB/s.
