Yeah, that’s largely due to hardware manufacturers’ and ISPs’ marketing teams wanting to show bigger numbers. “1 Gbps” sounds a lot cooler than “0.125 GBps”. But file sizes are almost always measured in bytes, not bits. And the difference between Gb and GB is subtle, at best. So a layman will easily assume that 1Gbps will transfer a 1GB file in 1 second.
And don’t even get me started on the difference between GB and fucking GiB…
The maximum real world speed for USB 2 is around 320Mbps or 40MB/s, but that only happens if there is only one device connected to the USB controller. 30MB/s is much more typical.

they are mixing gigabits with gigabytes so that is confusing. but even then, the math is still wrong for the usb 2 speeds.

Data communication speeds have always been in bits/second. No marketing teams involved, it’s just the most logical way.
I mean I don’t think I’ve ever seen USB 2 actually hit the 480mbps theoretical speeds, usually it’s much slower

Those are the bi directional bandwidth not the file transfer speeds going one way.
