I've got Seagate Barracudas (the 3TB version) and was a bit miffed to
realise that they didn't support this. That said, with mirrored 1TB
drives, you shouldn't have any real problems with SRC/ERC - the problem
is that a drive that returns 1 error per 10TB read is within spec, if
your array is over that size, then "good" drives could well cause a
crashed array if you have any glitches. (It seems that most drives are
well over spec, but why run the risk).
If you're price-conscious, WD Reds are not much more expensive than
Barracudas, and are advertised as "good for RAID". I'm looking at them
for my next hard drives.
Cheers,
Wol
