External Drive Question For Ibook G4 Options

[meadows.83]

i just picked up an 80gig owc external drive for use with my ibook g4. I have it up and running, and i know that you are supposed to keep the app(pro tools 6.4) on the internal drive, and the audio files on the external, but i was wondering if there was anything else that needed to be done in order to make things run the best, i.e., changing directories for saving files in pro tools? thanks for the help
