Names are fine, the problem is if you call something superspeed what are you going to call next years speed? Hyper speed? Ultraspeed? Turbospeed? You rather quickly run out, and that’s if it doesn’t start sounding ridiculously hyperbolic before that. And of course superspeed is super slow by todays standards.
So you have to either use marketing names that don’t mean anything by themselves, or numbers that naturally increase.
Well, USB-IF made a mistake with USB High Speed, Super Speed (+), Full Speed.
Since 3.2 it was pretty simple:
- SuperSpeed USB 5Gbps
- SuperSpeed USB 10Gbps
- and so on.
However, to use, those vendors must send devices for testing and compliance. Many just don't do certification because they don't want, and some don't do that because they're making straight up non-compliant: SuperSpeed USB 20Gbps a.k.a. USB 3.2 Gen 2x2 can only come in USB-C form.
USB 3.2 Gen 1x2 which has the same speed as USB 3.2 Gen 2x1, but it only comes in USB-C unlike USB 3.2 Gen 2x1. When you see a motherboard with USB-A ports and those specs - those are not certified.
Then Super Speed branding tells you nothing about Power Delivery.
Or even USB 1.1, which called the faster of its two modes (12 Mbit, or perhaps more honestly Mbaud, per second) “Full Speed”, at which point anything you name an even-faster one is going to be confusing.
So you have to either use marketing names that don’t mean anything by themselves, or numbers that naturally increase.
