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.
Benchmark Results: The Mushkin Callisto 60GB SSD was able to reach 241MB/s read and 202MB/s write. The random access time and CPU utilization were really low, which is what we like to see on SSDs.
Comparison Chart: The Mushkin Callisto 60GB SSD does very well and hangs right with the other SSDs that use the Sandforce controller. The vast majority of these recent SSDs are right around 240MB/s read and 200MB/s write. It’s tough to go wrong with most of these drives!
