I have to be sure, in order to connect my SDD properly: There are 4 USB-A connectors in pairs of 2 on my RPi4. The blue ones are 3.0 and the black ones 2.0?
Can anyone confirm this?

1I have seen in the specs link though that it are 'just' USB 3.0 ports. How can one distinguish them from each other afterwards? Is there a way to find out what's on my Pi from the command line?– Wolk9Commented Aug 19, 2021 at 14:45

The answer was yes (as said in the comments). For completeness, the more or less standard colors are
- White: USB 1
- Black: USB 2
- Blue: USB 3
I understood, that the Pi sometimes used white adapters for USB 2 though.
