HD Tach Testing
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 performance trend we've seen throughout this piece continues in the HD Tach benchmark. Here, once again, the SandForce based drives finish right on top of each other in terms of reads, writes, burst speeds, and access times, and the JMicron based Patriot drives trails the pack.
