As I mentioned, the RPi4B+ has a full USB 3.0 controller now, working 
with full 3.0 speed without interference from the Ethernet traffic 
anymore. I tested it, in fact I have a USB 3.0 external 2.5" HDD 
connected to mine, that's where all the data for my various SQL, email 
and web sites tests is... ;-)
