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."

HD Tach v3

OCZ Z-Drive m84  256GB
Intel X25-M x 2 RAID 0 160GB

ioXtreme 80GB

The first quick notable we'd like to make here is that, yes, again we can't provide you with two-drive ioXtreme RAID 0 numbers in this test because HDTach doesn't support the configuration on a formatted, Windows software RAID striped volume.  Though we could run the test, HDTach would still see two physical drives at the hardware level and bypass the software RAID stripe.  With that out of the way, the single drive performance of the ioXtreme is moderately impressive here, besting an Intel X25-M G1 RAID 0 array with two SSDs.  The OCZ Z-Drive never seemed to fair very well in HDTach however.
