I don't know if the reliability grade is true or not but what I can tell
you is that I have scsi drives that are 5+ years old that still work without
issue.

I have never had an IDE drive last longer than 3 years (when used in
production).

That being said, so what. That is what raid is for. You loose a drive
and hot swap
it back in. Heck keep a hotspare in the trays.
