Marketing Information

The USRobotics USB 3.0 ExpressCard easily adds 2 USB 3.0 ports to your laptop. Connect super speed peripherals like USB 3.0 external hard drives, digital video cameras, high-resolution webcams and save time with faster transfer rates of up to 5 Gbps. The blazing fast 5 Gbps transfer rate is up to 10 times faster than USB 2.0 (480 Mbps). The USB 3.0 ports are backward compatible so while the card is capable of super speed transfers, it also supports USB 2.0 and USB 1.1 speeds. Simultaneous transfers automatically detect USB type and transfer data at the maximum rate for each individual port.
