HD Tach Performance
Simpli Software's HD Tach is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives, 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 being tested."
The newly updated Intel X25-M second generation solid state drive with 34nm flash memory performed well in the HD Tach benchmark, clearly besting the previous generation Intel drive in write performance. The OCZ and Corsair drives offer better sustained write performance, however, the write patterns aren't nearly as smooth.
