HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible.
The SATA6 Testing was done using Crucial RealSSD C300 256Gb SATA6 SSD drive.
Benchmark Results: The SATA 6 performance of the ASUS P8Z68-V Pro average read speed of 299.87MB/s was about as close to the 300MB/s mark as you can get without crossing. The average write speed was a comfortable 200.93MB/s. Unfortunately, these numbers weren’t quite enough to keep up with the GIGABYTE P67A-UD7’s performance of 335.83MB/s read and 236.17MB/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 performance margins of the Average read speeds are quite similar to above. The GIGABYTE P67A-UD7 averaged 319.07MB/s while the ASUS P8Z68-V Pro averaged 283.8MB/s. The Average Write speeds in HD Tune were darn near identical (enough so that I went back and checked my numbers). The ASUS P8Z68 and the P67A-UD7 both were able to average just over 220MB/s.
