The Intel X25-M 80GB Solid State Drive Review

HD Tach v3.0.4

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 Benchmark Results

Benchmark Results: HD Tach showed that the Intel X25-M had the lowest Random Access Time of 0.1ms and the highest average read speed at 219.5MB/s. The next closest access was the VelociRaptor at 6.8ms. The pair of Western Digital VelociRaptor hard drives turned in the highest burst speed with a 413.3MB/s versus 261.1MB/s on the Intel SSD. The other hard drives included were unable to compete at this performance level as you can see by the results.  The CPU utilization on all the systems ranged from 1-4%, but the margin of error in this test is +/- 2%.
