I would definitely go for Red or other RAID/NAS type drives, because these are the only ones to have Time-Limited Error Recovery (TLER). Without this, your disk will hang for indefinite amounts of time when an error occurs. That means that a single sector read error can cause the entire disk to be thrown out of your RAID array, instead of letting the RAID system recover from the error gracefully.
