I've been editing a feature film for the last nine months using the Apple RAID card and four internal drives, then backing up nightly to an external drive via eSATA 1TB drive. 640GB OS, 3x1TB RAID 0 internal, 1TB external. I've decided to switch to an Atto or Areca card to replace Apple RAID Pro card, and get an external 4-drive box to build RAID 3, and use my four internals for OS, scratch, renders and original media files. Which RAID card would be best suited for an '09 Mac Pro with external raid? I don't need Windows or bootable external, as far as I'm concerned. I'd just use the internals for everything but RAID. I saw an Areca 1110ML for about $300 or so. Good choice, or is there newer and better for me?
