The internal hard drives on my 9000 Pro's are great for me - lots of space, nothing to carry/remember, no possibility of an accident from someone bumping into it. Some places I play have no stage and people can be really careless when dancing or just trying to get by me - I actually use right-angle audio cords in these places because I'm afraid someone will run into the back of my keyboard and break my plugs off if they stick out too far. When I used to sing they would inevitably run into my mic stand - they would do that to a thumb drive for sure.
