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 as possible.
Benchmark Results: The results for the HD Tach benchmark were somewhat surprising with the WarpDrive posting lower scores across the board than what we saw on the OCZ RevoDrive X2.
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
Benchmark Results: The WarpDrive had a little better showing here with the 4k numbers being very strong although relatively the same as the RevoDrive X2.
