Looking for some advice, and perhaps a pointer to instructions on best practices for setting up a RAID array on my (not yet received, darn it) mac pro. I'm due to receive in the next couple of weeks: 2.66 Mac Pro, 2 GB RAM, 500 GB HD, XT1900 card, wireless/bluetooth. I also just ordered 3 320GB Seagate 7200.10 drives from NewEgg (total cost w/ shipping and tax an amazing $305). The heavy apps will include photo/video editing (Aperture, Photoshop, FCP) on a 30" Apple Cinema Display (which is just sitting on my desk looking lonely -- waiting for that MacPro to arrive). While I wait, I figured I could gather some information on how to configure the drives when the box arrives. It sounds like you get quite a bit of performance enhancement from running a RAID 0, but failure is a great risk and therefore requires more backup. With 1.4TB of disk space, my hope is that I'll have sufficient quantity to run an efficient RAID while regularly (automated?) backing up for safety and security. I've got an external USB 300GB drive I currently use for backup purposes. Does anyone have any suggestions on how best to configure the setup to maximize speed and backup? I haven't yet found online any straightforward instructions for how to set this up in OS X so any advice would be greatly appreciated. Thanks!
