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 performance testing was completed using a Corsair Force GT 240Gb SATA III 6Gbps SSD.
Benchmark Results: The ASUS Z87-Pro averaged 496.1MB/s sequential read and 433.7MB/s average write, while this is a solid performance it is the slowest of all of the boards on the bench. The 4K Write was quite impressive though, with an average of 13.6MB/s.
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.
Benchmark Results: The ASUS Z87-Pro was able to step up its game and was able to pick up the second spot in HD Tune with an average read of 356.5MB/s and an average write of 325.3MB/s.
