I have installed ssd in my mbp and now need a scratch disk. Any advice on a set up? I will be editing on ilife 11 till the new final cut X comes out. I will be editing less than 16gb of video to at most 15 min video clips. What do i need for a scratch disk? I will use a firewire port (800). What size scratch disk do I need. Will I benefit from a SSD scratch disk since I am editing relitively small amount of video? At this time a could pick up a ~100gb ish ssd relativly cheap. if this is not a good idea what specs should I get for a scratch disk? 2.5/3.5? 7200 rpm? There was some post I found using Mroogle on scratch disk but the info seemed outdated.
