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 ADATA SP300 SSD connected to an Icy Box IB-223StU3 USB 3.0 enclosure. ATTO was the benchmark used.
Utilising the USB 3.0 ports provided by the Z77 chipset, Asus' P8Z77-V LX2 motherboard offers similar performance to its higher-priced siblings.
