Yeah I have some decently speedy USB-A 3.0 drives, they’re essential to me these days. Although I’ve filled them with too much crap to use as a boot drive for anything lol. They’re only 400MBps, but weren’t expensive.
One thing I’ve noticed though, it ends up saturating a pair of USB ports in a lot of computers. If I have a second thing in an adjacent port, eg a mouse, things get screwy (mouse movement gets choppy or speeds throttle).
