USB 3
USB 3 is designed to be backward compatible with earlier versions of USB cables and ports. USB 3 has different shaped connector pins, so it can withstand more frequent use. The USB 3-A and USB 3-B cables are the same as the USB-A and USB-B cables at the top of this article, just to distinguish that they are blue inside. The USB 3 micro cable has extra pins to enable more data transfer.
