Providing speeds up to 10x faster than that of USB 2.0, this PCI Express USB 3.0 card enables you to access your data and transfer files much faster than USB 2.0, by adding two USB 3.0 ports to your PCI Express capable PC.
Featuring a native NEC PCI Express host controller chipset, the new USB 3.0 standard supports transfer rates of up to 5Gbps, while still providing connectivity and support for the older USB 2.0 (480Mbps) and 1.1 (12Mbps) devices.
