@garetz: His calculations are just as valid if he buys redundant drives for a backup. It’s just a matter of putting a price on getting a unit replaced and having a guarantee that for X period of time, if a drive fails the replacement will be free. If you have a drive fail outside of the warranty you have additional costs to replace units.
