The major fallacy in that solution is that you're treating redundancy and backup equally. RAID doesn't protect you from a horked partition table, accidentally deleted file, or blown up power supply. In my mind, RAID is for data that you'd like some level of protection on but can lose, whereas a true backup solution is for data you just can't lose. Of course, a combination of the two is the most ideal approach for the most important data.
