No, there's no need to see red. It's real stuff. The biggest deal for
RAID is TLER (Time Limited Error Recovery) which makes sure that
drives keep responding so the RAID array doesn't drop the drive
unnecessarily.

These drives are 7200RPM, which you can probably get in a Green drive
if you look long enough. However they are rated for far more hours of
life also.
