I am planning on getting two 1TB LaCie Big disks for a RAID 1 (mirrored) array. How should I set it up? How taxing is it on my computer to run entirely on software (no hardware controller)? Can I still run FCP while controlling a RAID 1 setup via disk utility, or will it be slow? Can I set up my eMac to be a RAID controller and slave to my MBP? Even though its less space (500GB mirrored) should I get something like this? I would need a FW800 Express/32 card for my MBP. Help? I am being extremely indecisive. I like the "real" RAID system because if a drive fails its $178 instead of $589. On the other hand, I get more storage with the BigDisks. EDIT: can I set up the BigDisks in a RAID 5 scheme?
