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: There isn’t any real significant differences in the SATA III 6Gbps performance of our Intel Z77 Budget boards today. While the ASRock Z77 Pro3, BIOSTAR TZ77B, and GIGABYTE Z77-DS3H are all aimed at the more budget minded individuals, they all use the same SATA III 6Gbps technology available on the Intel Z77 chipset. With that being said, the GIGABYTE Z77-DS3H was able to take a slight lead in the sequential read with a performance of 497.0MB/s compared the the ASRock Z77 Pro3 494.7MB/s and the BIOSTAR TZ77B performance of 492.6MB/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 Results: Our results in HD Tune 5.00 tell a similar tale as the one we heard in CrystalDiskMark above, no significant differences between the SATA III 6Gbps performance of our Intel Z77 Budget motherboards.
