ASRock Z87 Extreme9/ac Motherboard Review

With its emergence as the new standard for high-speed portable devices, USB 3.0 performance on a modern motherboard needs to be good to ensure that data transferral bottlenecks aren't created.

We tested USB 3.0 performance using an Kingston HyperX 3K SSD connected to an Icy Box IB-223StU3 USB 3.0 enclosure (ASMedia ASM1051 controller). ATTO was the benchmark used.

Using ASRock's XFast USB software, the Extreme9/ac motherboard's USB 3.0 ports are capable of delivering transfer rates in excess of 250MB/s. This is a big improvement over MSI's Z87 XPower which doesn't offer any form of UASP software.
