I'm thinking of updating from my 06 2.66 Mac Pro to a 27" iMac 2.8 with 8 gig's of ram and the 2 terabite drive. The Pro has 9 gig's of ram and 3 internal drives, one is the system stuff the other is the Aperture library the 3rd unused to small. I also have 4 ext. drives with iTunes, iPhoto, Aperture back up and Time Machine back up. I have the 30" display but it's on it's way out starting to get grey banding and needs to be replaced any way. The machine is not used hard, light photo work ect. Couple of question when I move everything over will I be able to move the Aperture stuff at the same time? And I'm going to have more USB's than ports. One of the drives can go to firewire but the other 3 will take up the rests of the ports so no place for card reader scanner ... ect. Guess a powered USB bus will be the answer to that. Does this sound like a smart move? Currently plugged into the Mac Pro printer, scanner, 4 drives, Iphone/iPad cord, card reader. Any ideas on a good powered USB port? Like to make this a neat setup not a jumble of wires. Thanks I've been a Mac guy for awhile we currently have 3 iPhones, iPad, Mac Mini ( hooked to TV), 27" iMac (daughters), MacBook Air (wifes) plus my Mac Pro.
