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.
The SATA III 6Gbps Testing was done using OCZ Vertex 3 120GB SATA6 SSD drive.
Benchmark Results: The ASUS P9X79 Pro had a solid Sequential read of 471.6MB/s and Sequential Write of 177.7MB/s. These aren’t the fastest numbers that we have come across but they are still quite respectable.
HD Tune Pro 4.01 is an extended version of HD Tune which includes
many new features such as write benchmark, secure erasing, AAM setting,
folder usage view, disk monitor, command line parameters and file
Benchmark Results: In HD Tune 4.61 the ASUS P9X79 Pro had an average read of 493.3MB/s and an average write of 443.9MB/s. Once again they don’t break any records, but the performance is still incredibly fast. The Intel X79 chipset doesn’t really have any performance improvements for SATA III over the Intel P67/Z68 platforms, but comparing it to the Intel X58 platform there is a world of difference. The Sandy Bridge platforms all feature an integrated SATA III controller while the Intel X58 platforms were forced to use a third party controller like the Marvell PCIe 9128 controller found on our ASUS Sabertooth X58 motherboard.
