[ale] Copy time for USB ext HDD

[Richard Bronosky]

Many of the USB2 hubs will function at the "lowest common
denominator". Meaning, if you have any USB1 device plugged in
(keyboard, mouse, joystick, USB humping dog, etc.), you get USB1
performance out of everything. That may not be the situation with
every hub, but the 2 I've owned were that way.
