Anyone tried charging their Droid via a USB 3.0 port? I have an open 3.0 port and I think it puts out 900 mAmps where the standard wall charger is 850 mAmps. BTW, if you've got a device that supports it (like a newer external HD), I'd highly recommend USB 3.0. I copied a bunch of jpeg photos from C drive to external drives. One a Western Digital My Book 1 TB drive on USB 2.0. The other a Western Digital My Book 2 TB drive on USB 3.0. Both hooked up to my computer (Dell XPS 630i). 446 files in 12 folders. 948 MB total. On drive connected via USB 2.0 it took 1:12.52 to copy to drive. On drive connected via USB 3.0 it took 18.48 to copy to drive. That's a lot faster (a quarter of the time or so) and $30 well spent IMO for the 3.0 card.
