ADATA DashDrive Durable HD650 500GB Review (Page 6 of 8)

Page 6 - Benchmark: HD Tach

About 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.

HD Tach's sequential read performance is very much a 'drag race' approach to evaluating storage performance, but it is still a valuable approach to provide insight when comparing one drive to another. From above, you can see we were able to hit 120MB/s read at peak at the beginning of the drive, and decreasing to just under 60MB/s. This averages out to 94.8MB/s. You might wonder why the graph is actually curved, considering all our flash drives are practically flat lines. This is because this is a traditional hard drives, and thus speeds will decrease as we move further away from the center. In terms of burst speed, we were able to hit a very respectable 188.2MB/s. Comparing once again to our Silicon Power Armor A30 1TB, the ADATA DashDrive Durable HD650 500GB is actually faster for both average read and burst speed by around 10MB/s. This is a bit of a turnaround from the other tests, but remember this is a different format of testing storage performance, and thus each drive has their pros and cons. I should also point out the tested latency time is around 17.4ms.
