When multiple devices are connected, traditional single-bus USB cards share the maximum bandwidth between all ports. By employing two host controller chipsets, shared across two ports rather than four, this 4-port PCIe to USB 3.1 card dedicates up to 10Gbps for each set of two USB ports. It reduces performance bottlenecks and doubles your total available bandwidth to 20Gbps.
With higher data throughput support, the card is ideal for external hard drives, hard drive enclosures, and large external storage devices. It lets you access multiple devices simultaneously for read and write access.
The 4-port USB 3.1controller card adds dual independent channels to your computer and shares 10Gbps of bandwidth between two USB ports.
Each set of two ports shares a combined bandwidth of 10Gbps. If a single device is accessing the channel, the card will provide data transfer rates of up to 10Gbps to the device. If two devices are accessing the channel simultaneously, the 10Gbps of bandwidth will be shared between both devices.
