usb 3.0 vs usb 3.1

USB 2.0 was only capable of a theoretical maximum data transfer rate of 480 megabits per second, while USB 3.0 was capable of 5 gigabits per second, or over 10 times faster. ... The data transfer speed of USB 3.1 is incredible – 10Gbps. This rivals the speed of Ethernet and the original Thunderbolt.Dec 1, 2015
