USB 3.0 Performance
Moving onto USB 3.0 performance using HD Tune Pro 4.6 and a LaCie external USB 3.0 drive, we found that the average read speeds were mostly similar for all three boards (USB 2.0 was obviously lagging behind). The Gigabyte board however was significantly slower when it came to write performance, with both average and maximum speeds falling behind. Random access speeds were generally similar between the three configurations as well.
Additionally, we have to mention that the ASRock comes with an EtronTech USB 3.0 controller unlike the NEC controller on both the ASUS and Gigabyte. Though not conclusive, It could perhaps explain the slight differences in maximum speeds achieved by the ASUS compared to the ASRock since the former has adequate bandwidth with its bridge chip.
