It might be tricky to set up. You can't just run the game there and play. You need to install it onto the USB drive while updating the PC's registry. Yes, you could do it, but it wouldn't let you play the game on someone else's computer from the USB—it would only function on the original machine.
It would take longer compared to an internal drive, but possibly quicker than an external one. It can't just be plugged in automatically, but if you have all the game files ready, you can set the origin on the drive and it should work without issues.
