About HD Tach 126.96.36.199
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.

While HD Tach's sequential read performance is more of a 'drag race' approach to evaluating storage performance, it still provides valuable insight into how good a drive is compared to the next. From that above, I was able to pull a very good 120MB/s at the beginning of the drive; steadily decreasing to just over 60MB/s at the end of the drive. This worked out to an average of 92.2MB/s. This was very close to the ADATA DashDrive HV620 1TB and Silicon Power Diamond D06 1TB, and slightly faster than the Silicon Power Armor A30 1TB. It is interesting to point out both the Armor A30 and Diamond D06 both have the same hard drive inside as the Armor A65. Up until a few years ago, this would have been the performance curve of a pretty fast SATA internal desktop drive; definitely not something you would expect from an external 2.5" 5400RPM unit over USB. As you can see in our screenshot above, the tested latency was 17.0ms, which is the same as our AIDA64 results on Page 3 of this review. Once again, I am quite happy with the performance Silicon Power Armor A65 1TB.
