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 RunCore Pro V again shows the same performance as the other SATA II based SF-1200 drives we have tested. It doesn’t look like anyone is going to squeeze more performance out of this controller.
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 4k write score was slightly below what we saw on similar drives but close enough that no real world difference would be discernable.
