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: For the most part we aren’t seeing much variance between the SATA III 6Gbps performance across the Intel Z77 motherboards. The ASUS P8Z77-V Deluxe did pull away from the crowd with a sequential read speed more than 25MB/s faster than the next board. The sequential write speed of the P8X77-V Deluxe was also faster, though only by 4.3MB/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: Once again the ASUS P8Z77-V Deluxe pulled away from the rest of the Intel Z77 motherboards by a solid amount. The BIOSTAR TX77XE4 and the GIGABYTE Z77X-UD5H were 25MB/s (BIOSTAR) and 16.9MB/s (GIGABYTE) behind the ASUS board while the sequential read of the MSI Z77A-GD65 was considerably slower with 351.9MB/s.
