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.

As you have read from past reviews, you would know HD Tach’s sequential read performance is very much a ‘drag race’ approach to evaluating storage performance, but it does provide some insight when comparing different drives to each other. From above, you can see for the most part, the graph is a flat line. The small fluctuations are between 27MB/s and 30MB/s, and average out to exactly 28.5MB/s read. Burst speed is a bit higher at 34.0MB/s. In comparison, the Kingston DataTraveler Locker+ G2 is a much slower average 16.9MB/s, while the maximum burst speed is at 18.4MB/s. Finally, the OCZ Rally2 Turbo 4GB averages at around 32.8MB/s, and 33.9MB/s for burst speed. Once again, these results line up with our other benchmarks, and are not too surprising overall. A thing to note is the random access time, which measures at around a speedy 0.4ms. In fact, these numbers are quite close to USB 2.0 drives, which is expected, as it is not interface limited.
