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 SuperSpeed USB 3.0 performance testing was done using a Corsair Force GT 240GB SSD.
Benchmark Results: The GIGABYTE Z77X-UD5H and the GIGABYTE Z77X-UD3H were spot on with our first Intel Z77 motherboard that we tested. The GIGABYTE Z77X-UD5H had a sequential read of 252.3MB/s and a sequential write of 252.1MB/s. The GIGABYTE Z77X-UD3H was slightly faster with a sequential read of 254.0MB/s and a sequential write of 257.3MB/s. The ASUS P8Z68-V Pro which uses the ASMedia ASM1042 USB 3.0 controller wasn’t quite holding a candle to the Intel Controller and gave us a sequential read of 22.4MB/s and a sequential write of 230.7MB/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: The GIGABYTE Z77X-UD5H and the Z77X-UD3H both were at the top of the charts for average read speeds. The GIGABYTE Z77X-UD3H took the top spot with 264.0MB/s and the Z77X-UD5H was close behind with 262.1MB/s. The Average write speeds of the two boards were solid with the Z77X-UD3H the top of the two with 245.2MB/s and the Z77X-UD5H with 241.5MB/s. The MSI Z77A-GD65 maintained the top spot with 261.8MB/s.
