I have been using HDTach for many years now and always find it is an invaluable benchmark to ascertain potential levels of performance. 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.
Similar results to the previous ATTO Disk tests, with the drive struggling to maintain an average of 100 MB/s. This is rather disappointing for a 3.5 inch 7,200 rpm mechanical drive.
