Page 6 - Benchmark: HD Tach 3.0.1.0
About HD Tach 3.0.1.0
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 what we would call a 'drag race' approach to evaluating storage performance, and it provides a valuable approach to provide insight when comparing different products to each other. From above, you can see we were able to hit 120MB/s read at peak at the beginning, and decreasing to around 58MB/s. This averages out to 84.7MB/s. Of course, your first question might be why the graph is actually curved, considering all our flash drives our practically flat lines. This is because this is a traditional hard drive, and thus speeds will decrease as we move further away from the center of the disk. In terms of burst speed, we were able to hit a very respectable 177.6MB/s. Comparing once again to our ADATA counterpart, 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 way of testing storage performance, and each device will perform better in different areas. I should also point out the latency time, which is 17.4ms.
