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 (ASMedia ASM1051 controller). ATTO was the benchmark used.
Due to its absence of UASP-activating software, the USB 3.0 transfer rates using MSI's X79A-GD45 Plus motherboard are not particularly strong. It would seem that the Renesas D720202 USB 3.0 controllers are not as strong as their ASMedia counterparts – not when used on the MSI X79A-GD45 Plus motherboard, at least.
