Moving data to and from an external device is something we all do as a means of backing up sensitive data, whether it be family pictures, movies, music, or projects. The speed with which this transfer occurs is measurable and can improve with different tools. I will be using ATTO version 2.47 to measure an external drive's read/write performance through the USB 3.0 interface. The default test algorithm is used for this test. Motherboards that support a boost to the USB spec, such as USB 3.0 Boost on the ASUS offering and XFast USB on the ASRock, will be used as they show the maximum potential speeds.
The results in this test are interesting, as they show how well each manufacturer's USB 3.0 speed boost technology works. ASUS' implementation has the edge in larger file sizes, while the Extreme 4 does incredibly well using smaller file sizes. Overall, using Turbo Mode in ASRock's XFast LAN software is one way to increase throughput throughout the whole usage range, although if you are transferring data to and from an external drive, you most likely are using larger file sizes. Either way, the boost in performance is a point of difference.
