- USB 3.1 Gen 2 is the same as USB 3.2 Gen 2 and is only found at 10Gbps.
- The 40Gbps entry is wrong, the real spec name is USB4 Gen 3x2. But it was never really advertised as such so I'd leave that out.
- 20Gbps is either USB 3.2 Gen 2x2 or USB4 Gen3x1, but I'd caution against adding this as the latter is quite rare to see (plus the above reason).
For the quiz, I would split up connecting storage devices and PCIE enclosures. Most storage only goes up to 10Gbps, and it will specifically say if it's built for Thunderbolt.

Did you confuse the latter with the former perhaps? I have never seen USB 3.2 Gen 2x2 in the wild. I have just bought a 20 Gbps USB4 cable, connected my laptop with my Android phone using it and it works lightning fast (as compared to USB 3.2 gen 1).
Here's a Gen 2x2 SSD [1] but I can't seem to find a reliable listing for a cable, the general consensus is just to use what comes in the box.
At this point I'd only buy cables that come with the right logo stamped directly on it like this one [2].
The USB versioning table needs some corrections:
- USB 3.1 Gen 2 is the same as USB 3.2 Gen 2 and is only found at 10Gbps.
- The 40Gbps entry is wrong, the real spec name is USB4 Gen 3x2. But it was never really advertised as such so I'd leave that out.
