Gigabyte's UASP USB 3.0 driver boosts USB 2.0 performance

There are of course a couple of limitations involved, for one, you need a Gigabyte motherboard with a Renesas/NEC USB 3.0 host controller and secondly you need to install the latest drivers from Gigabyte. We used an external USB 2.0 hard drive for our quick test and plugged it in to the USB 2.0 ports connected to the P55 chipset, as well as the Renesas USB 3.0 host controller ports.

We didn’t expect to see much of a difference in terms of performance, but we were pleasantly surprised. A simple file copy test from an internal SATA drive of a 550MB file took 20.9 seconds using the USB 2.0 ports while it took 17.7 seconds using the USB 3.0 ports. Maybe not a huge performance increase, but if you copy a lot of data, then it all adds up.
