Comment on Some basic info about USB
Plopp@lemmy.world 2 months agoBehind the scenes, here’s what those labels correspond to:
USB 5Gbps: USB 3.0 and 3.1 Gen 1 USB 10Gbps: USB 3.1 Gen 2, 3.2 Gen 2×1, and 3.2 Gen 1×2 USB 20Gbps: USB 3.2 Gen 2×2 USB 40Gbps: USB4’s initial version as currently shipping
That’s cool. But even though it finally adds simplicity, it’s still yet another renaming of the same things.
Here’s a snippet from an article from 2019:
The upcoming 20 Gb/s USB 3.2 connection, which offers twice the speeds of the previous iteration, will be known as ‘USB 3.2 Gen 2x2’. Its predecessor, ‘USB 3.1’ will be rebranded to ‘USB 3.2 Gen 2’, while ‘USB 3.0’, which ran at 5 Gb/s speeds, will be termed ‘USB 3.2 Gen 1’.
Reading that I want to shoot myself, and even the latest change, which probably is a good one, drives me slightly mad due to the history of renaming everything so many times.

Every time a new USB spec comes out the version number goes up. A new spec comes out because they add more features. The spec is a whitepaper that explains all the features.
If you just never used the version numbers to mean something that they never meant (transfer speeds) then literally none of this is confusing.
They’ve officially renamed the transfer speeds one time after people made a big huff. here’s how they changed:
USB SuperSpeed -> USB 5Gbps
USB SuperSpeed 10Gbps -> USB 10Gbps
USB SuperSpeed 20Gpbs -> USB 20Gbps
And If you can’t follow along with that, I’m really, really sorry. There’s not much I can do from a internet discussion board. XD
