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 Phoenix Pro showed well here with minor variances in the performance as the test progressed. The overall scores posted were solid as well being among the top of all drives in the data grid.
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: Scores among the SandForce drives are essentially identical and this is one of the few benchmarks where for the most part they lag behind some of the Indilinx and JMicron drives.
