I use a G5 for recording. I have reached the stage where it is crucial to save all my recordings on two hard drives in case one drive crashes and I lose valuable files. My question is: will I use two hard drives daisy chained using Firewire 800 or use a RAID system. I need to save simultaneously to both drives. On re-opening files I need any changes made/new information to save to both drives. I'm sure you get the drift of my question. As you can gather from my question I am fairly new to Apple computors. I would really appreciate your help on this.
