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 GIGABYTE A75-D3H SATA III performance in CrystalDiskMark wasn’t quite up to that of the GIGABYTE Z77-DS3H. Though it was able to average 471.1MB/s sequential read and 297.3MB/s sequential write which is nothing to shake a stick at.
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 we see that the average read of the GIGABYTE A75-D3H is still slower than the Z77-DS3H. The average write on the other hand, shows that the A75-D3H is more than 20MB/s faster.
