These things are sooooo small that you don't see them in the socket, which is a neat thing. The big advantage is that your USB drive is almost like having a built-in HD in the keyboard without the problems and expense of an HD. I purchased the 4-gig model, but you can go much larger without increasing in physical size. I have one for each keyboard and unless I need to add some style files or registrations, they'll never be removed.

Cheers,
