I am building my personal private cloud. I am considering using second hand dell optiplexes as worker nodes, but they only have 1 NIC and I'd need a contraption like this for my redundant network.
Then this wish came to my mind. Theoretically, such a one box solution could be faster than gigabit too.
I just have that happen in general with USB NICs. Random drops for seemingly no reason.
They're not meant for infrastructural use, just as travel adapters.
