USB 2.0 size
USB 2.0
480 Mbit/s, 2.5 W (500 mA at 5 V)
Released in 2000 and still ubiquitous, because it is fast enough for keyboards, mice, printers and audio interfaces and cheap to implement. A USB-C connector does not imply anything faster — a great many USB-C cables and ports are USB 2.0 internally, which is why an external drive can be slow despite having the right plug.
