Everything about this USB3 3.0 board screams speed. It has four independent USB controllers for maximum simultaneous bandwidth. The NEC/Renesas controllers are Intel® xHCI compliant for efficient data transfer. And these are coupled to a four-lane, Gen2 PCI Express host interface. This board is ideal for communicating with up to four high-bandwidth devices simultaneously.
(The 8-port board is shown in the image above. The 4-port is identical, less the 4 internal ports.)
