Hi everybody. I have a new mac pro, stock 320 drive. I have been using an external 500 gig for video to stream to Apple TV. Now, I just got a 1TB internal seagate with 32 MB cache. I believe this is faster than the stock 320 drive. Should I make this the start up drive? I was going to use it for video, or partition it and use Time Machine on part of it. With this setup, what is the best way to go? My main goal is to have Time Machine and room for video in a orderly setup. What would you do? Thanks!
