Hi all. Im about to drop the hammer on a mac pro and have a question about setup for my drives. I am a graphic designer and photographer so speed, storage and backup are paramount. Here is what I'm thinking: 2 750GB drives Raid 0 for main volume 2 500BG drives Raid 0 for scratch disk Heres my main question. I want 2 separate externals for backup and daisy chain them. Will Time Machine backup to 2 daisy chained externals? For you PS geeks out there, does this sound like a good setup for the scratch disk? I'd love to go SAS, but just cant afford it. Thx in advance. - Sean Paul.
