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, allowing it to get as close to the physical performance of the device as possible.

From: Developer's Page

As we always mention here at APH Networks, HD Tach uses “drag-race” approach for performance evaluation and not necessarily indicative of real life performance, it still provides valuable insight into the performance of a drive. As we can see from the screenshot above, the average read speed was 128.9 MB/s, and the burst speed was 133.4 MB/s. Again, there were no surprises regarding the data rate. The random access delay was 0.9 ms, which is pretty close to the AIDA64 Disk Benchmark's 1.08 ms tested latency. In real life applications, the difference between 0.9 ms and 1.08 ms is negligible.
