The USB3.0 standard provides ten times the transfer speed and higher energy efficiency than USB 2.0, and can be widely used in PC peripherals and consumer electronics. The theoretical bandwidth of the USB3.0 interface is increased to 5Gbps, while the theoretical bandwidth of the USB2.0 interface is 480Mbps. All high-speed USB2.0 devices will perform better with USB3.0.
