Simplicity is over-rated, or at least, that’s what USB-IF appears to think. USB-IF is the industry body that defines UBS nomenclature and specifications. For some reason that makes no sense to us mortals, they seem to have made it their mission to completely muddle up USB specifications in the consumer world. See, things were much simpler before. You had USB 1.1, USB 2.0 and USB 3.0. Clearly, the USB version with a higher number was better. Rather than continue that trend, USB-IF then introduced USB 3.1 and muddled things up. Then they decided that things weren’t confusing enough and introduced USB 3.2 and made everything worse.
- USB 1.1 (Full Speed): 12 Mb/s
- USB 2.0 (High Speed): 450 Mb/s
- USB 3.0 (SuperSpeed): 5 Gb/s
- USB 3.0 became USB 3.1 Gen 1: 5 Gb/s
- USB 3.1 Gen 2 (SuperSpeed USB 10 Gbps): 10 Gb/s
And now it’s become:
- USB 3.0, formerly USB 3.1 Gen 1, is now USB 3.2 Gen 1: 5 Gb/s
- USB 3.1 Gen 2 is now USB 3.2 Gen 2: 10 Gb/s
- USB 3.2 Gen 2x2 (SuperSpeed USB 20Gbps): 20 Gb/s
- USB 1.1: 12 Mb/s
- USB 2.0: 450 Mb/s
- USB 3.0: 5 Gb/s
- USB 3.1: 10 Gb/s
- USB 3.2: 20 Gb/s
