I work alot in FCP and will soon be traveling for work and plan to buy a MBP C2D 17". My questions: 1. Is it worth it to upgrade to the 7200RPM internal drive (this will mean buying a BTO new machine - very $$$ I can settle for refurb/5400 RPM) Will FCP work OK (render, play) with the 5400 internal drive OK? Will I notice a HUGE diff in FCP performance (rendering, RT playthrough) 2. For external storage - I am thinking of a FW 800/USB/eSata 2.5 enclosure and 5400/7200 drive. Will I need the 7200 drives for FCP (to do work on the road) or will the 5400 drives do ok? $ is the main issue here. With 5400 drives I can save ALOT of $ What am I basically asking is: Do I *need* the 7300 rpm or will 5400 be "usable" - i know this is highly subjective ;-) Will the FW 800 be fast enough or do I need eSata? I figure to use FW 800 in places I can't plug in and esata in the hotel.
