Interestingly, I was just browsing this paper
http://www.cs.utk.edu/%7Eplank/plank/papers/CS-05-569.html which appears
to be quite on-topic for this discussion. I admit my eyes glaze over
during intensive math discussions but it appears tuned RS might not be
as horrible as you'd think since apparently state-of-the-art now
provides tricks to avoid the Galois Field operations that used to be
required.
The thought that came to my mind was "how does md's RAID-6 personality
compare to EVENODD coding?"
Wondering if my home server will ever have enough storage for these
discussions to become non-academic for me, :-)
The problem is not having storage, it's having backup. The properties of
backup are
- able to be moved to off-site storage
- cheap and fast enough to use regularly
Making storage more reliable is a desirable end, but it doesn't guard
against many common failures such as controllers going bad and writing
unreadable sectors all over before total failure, fire, flood, and
software errors in the kernel code. While none of these is common in the
sense of everyday, they are all common in the sense of "I never heard of
that happening" response.
