Same series ... failing in the same afternoon after 10 months of service ! I can only repeat myself: Most people argue "but its two devices, its statistically independent". Well, two devices(*) manufactured at the same time and on the same assembly line (preferably with consecutive serial numbers), running the same firmware-version, bought at the same time, used in the same array with the same external stress and the same usage patterns. Even all my non-mathematical-non-informatics friends know that this isn't what you call "statistically independent". (*) Doesn't matter if its disks or switches or motherboards or processors or memory chips or power supplies or ups or backplanes or power-distribution-boards. If you "remove" your spof by using two of the exact same kind, statistics (and sad experience) say that its still a spof. So, subs (or is it "Mailing Lists":) and probably Brian, thanks for another data-point of this never-happens-in-real-life-scenario. We feel with you for such scenarios.
