"USB C" only describes the connector and has nothing to do with speed.
Yes and no. USB-C is "the faster connector" compared to USB-A 3 because it supports faster protocols like USB 4 and even Thunderbolt 5. USB-A does not. It tops out at USB 3.2 Gen 2x2 (gawd what an awful naming scheme) with 20Gbps and even that’s rare. The newer, faster protocols with 40Gbps (USB4) or even 120Gbps (TB5) need the USB-C connector.
It supports faster protocols, yes. But "USB-C" on it's own just defines the plug and the socket, and nothing more. That the hardware supports faster protocols does not mean that it can be used to describe a faster connection.
It's nitpicking, but it is important nitpicking 🙃
The point here, for those downvoting this post, is that if you go out and buy something "with USB-C" it could for example only support the Low Speed rate of USB 1.0 (that's all of 1.5Mbps, only good for stuff like mice and keyboards) and still be absolutelly legitimatelly be listed for sale as "having USB-C" because that's just the connector format.
(Actually it's even worse, as there is a charge only mode for that connector which does not require supporting any USB data modes at all)
There is indeed a connection between the connector (pun not intended) and the maximum speeds supported (but not necessarily present) because USB-C adds additional data lines not present in USB-A or any of the USB-B connectors, which allow higher data throughtput, but the connection is only in the direction of "higher speeds require USB-C", not "USB-C implies higher speeds".
All this to say that, IMHO, the previoua poster is right in calling attention to the difference.
Yeah I’m aware but you cannot support the fastest speeds without the additional contacts a type C port provides; unless they went with a proprietary port they wouldn’t be able to do the faster USB speeds.
So while type C doesn’t mean fast by itself, it does allow the capability to carry just about anything.
