HD Tach & CrystalDiskMark Synthetic Benches
HD TACH 188.8.131.52
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: Surprisingly, the RevoDrive X2 didn’t take any of the top scores here but didn’t miss out by much. For the most part, all of the SandForce drives perform pretty much the same regardless of their configuration.
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: CrystalDiskMark also uses incompressible data which doesn’t allow the controller to perform at its best but the X2 handily smoked all other drives in the sequential read/writes and nearly took the other top scores in the 4k tests as well.
