What is HD Tach?

HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), 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 possible.

The trial version of HD Tach measures the sequential read speed (at various points on the device), the random access speed, interface burst speed and CPU utilization of the drive. The registered version adds sequential write testing.
