Fun fact
Because the left half is a standard Micro-USB, an ordinary Micro-USB cable still works with these drives, just at USB 2.0 speed.
Tips & tricks
Lost the cable? A regular Micro-USB lead plugs into the narrow half and the drive will still mount, only slower.
Philosophy
Backward compatibility made physical. Ugly, but it never stranded a single old cable.
