Honestly, I think it makes far more sense to build a fault-tolerant setup than to try to avoid faults by spending more on the parts. I've only run desktop hard drives on my 24x7 RAID. If they die I replace them under warranty - I've yet to have one die outside of warranty, and I'm usually upgrading for size by that timeframe anyway, and I can use the old drives for storage. By all means get better-grade components, but I wouldn't use that as an excuse for not having backups of some kind. ALL hard drives WILL fail, it is just a matter of when. ANY hard drive can fail the day after you buy it, a month after you buy it, and so on, though obviously the probability of a particular drive failing at any point in time may vary by what you pay for it. I'd buy a more expensive drive only if the TCO is actually lower. I'd engineer any system to accept the failure of at least one drive, and for any data I actually cared about I'd engineer the system to resist fire, the rm star, and so on. Rich
