ASUS Crosshair IV Formula 890FX Chipset Motherboard Review

USB3 Testing

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.

Benchmark Results: The ASUS Crosshair IV Formula had slightly faster average read and write times when using the USB3 ports. The burst speed was nearly 18MB/s faster while the CPU usage is too close to compare since both systems are within the margin of error.

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.

Benchmark Results: There is very little
performance difference between the ASUS Crosshair IV Formula and the ASRock 890GX Extreme3 USB3 performance, though our results in HD Tune are very similar to those of HD Tach above, where the biggest difference is in the burst speed which is faster by 28.1MB/s on the ASUS Crosshair IV Formula.
