Gigabyte Z87-D3HP 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 ADATA SP300 SSD connected to an Icy Box IB-223StU3 USB 3.0 enclosure (ASMedia ASM1051 controller). ATTO was the benchmark used.

Gigabyte's Z87-D3HP doesn't use any type of UASP-activating software to unleash an additional 25%-or-so of performance from a USB 3.0 device that is fast enough. The performance of our ADATA SP300 SSD was capped around the 200MB/s mark instead of the circa-250MB/s it would have achieved on a board that supports the UAS protocol.
