For use with my MacPro, I'm using a single FW800 ext 1TB drive. thus no redundancy and no off-premises capability. 2 partitions, one is bootable clone of MacOS/apps, the other is for TimeShare. For convenience (has to be convenient, or I won't do it), I am thinking of a dual drive raid box with swappable drives (LaCie 2Big, G-safe). I could mirror the drives. Then get a 3rd drive which I could rotate in and store in a secure location. my concern about these products is noise and reliability. I've seen mixed reviews. LaCie in particular seems to get bad marks for quality, e.g. failures, etc What to you think?
