Storage devices are hardware, and Six Sigma be dammed, hardware fails.<br><br>AFAIK you'll have a hard time finding anything but anecdotal evidence about which brands / models last longer. I know some sys admins like to space out their HDD orders because they know some batches are bound to be bad.<br><br>You *could* go crazy and build a RAID 6 controller (fault tolerant at <= 2 simultaneous drive failures).
