The first thing to realise about USB-C is that it’s not a new USB standard in the same way as USB 1.1, USB 2.0, USB 3.0 or the very latest USB 3.1 are. Those upgrades focus on defining what the connection can do in terms of speed and feature improvements, whereas USB-C is all about the physical connection, like with microUSB and miniUSB.
The crucial difference here, though, is that unlike micro and miniUSB, USB-C is aimed at being a replacement for both ends of the cable. More on this later.
USB Type-C received another big boost in the form of Thunderbolt 3. In June 2015, Intel revealed that its latest version of the port would piggyback on the new USB Type-C connector, giving it all the benefits and a new reversible look. It’s not all smooth sailing though – as Thunderbolt requires circuitry in the cable itself, it won’t be fully interoperable with Type-C.
Thunderbolt is a lot faster – well, four times – than the USB 3.1 standard which Type-C is built upon, which will obviously give plenty of benefit to those who need to transfer lots of big files very quickly.
