USB 2.0, released in April 2000, added a 480 Mbit/s High Speed mode on top of USB 1.x's rates -- a 40x jump that made USB viable for external hard drives and other high-throughput peripherals for the first time. It remains the fallback data rate on many budget cables and low-power devices today.

Originally released as USB 3.0 in November 2008, this 5 Gbit/s "SuperSpeed" tier was retroactively renamed USB 3.2 Gen 1x1 when the USB 3.2 specification arrived in 2017 -- the first step in a naming scheme many found more confusing than clarifying, since the underlying hardware and speed never actually changed.
