I wonder if you can use this fact to make drive which are more likely to fail later, actually fail sooner. I'm thinking that I could run my new drives in a fridge for a month or two or three - if they fail, I'll return them, else I can be more sure they'll last their expected life and not give me any trouble. Does that make any sense? Also, I see people recommending enterprise disks, which makes me think that those same people have forgotten what the 'I' stands for in 'RAID'. Of course, 'inexpensive' is relative - probably to one's income and it seems some people are paid more than others....it almost suggests we should have another acronym - RADCD - redundant array of dirt cheap disks. :) Max.
