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.
Not all motherboards in this test offer USB 3.1, which explains why these graphs are not as big as the others. The achieved speeds are clearly not as high as we see with high-end boards. All suited boards achieve about 690 MB/s when reading and 750 MB/s when writing; only the ASUS B250G and H270F perform slightly worse.
