USB 3 Facts
Transfer Speed: USB 3 is capable of a maximum transfer speed up to 5 Gbps. This is 10x faster than the USB 2.0 transfer speed
of 480 Mbps.
Bandwidth: USB 3 features two unidirectional paths; one for transmitting data and one for receiving data. USB 2.0 features only
one bi-directional path and must switch between transmitting or receiving data.
Compatibility: USB 3 devices and connections are backwards compatible with USB 2.0 devices and connections.
