USB connectors all used to look the same a few years ago. However, a new type of connector emerged called USB-C that delivers faster transfer speeds than its older brother, USB-A.
USB-C is now the industry standard, enabling users to transfer data in a speedy fashion and output video at higher resolutions and faster refresh rates. It's worth noting that the fastest USB-C connectors support the Thunderbolt protocol, so look for this if you're in need of a particularly zippy USB-C hub.
