Benchmarks (USB 3.1)
Since USB 3.1 is not a part of the chipset, the motherboard manufacturers have to use extra controller chips in order to support the new interface. We use the Sandisk Extreme 900 960GB, the fastest external SSD available at the time of writing, to test the speed of this interface. In contrast to previous test we also no longer perform this test with C-states set at C8, instead we use the default settings of the motherboard.
Only two of the four boards support USB 3.1: the ASUS and ASRock boards. The performance of the ASUS board is clearly better compared to the ASRock board, even though both boards use the same ASM2142 USB 3.1 controller.
