Being a personal user, and having close to a 10% RMA rate on recent
hard drives, that would be a bit costly...

I consider a HD defective if it's under waranty and it's performance
drops below 80% of new, i.e. 130MB/sec normal sequential write drops
below 100MB/sec..

The weekest point is the passphrase/passfile protecting the master
key... In my case, I use a random passfile for these drives...  If
someone is able to break the passfile, or the AES-256 encryption, then
they must really want my data...  It'd be easier, even for governments,
to do a black bag job than recover partial data (it's one drive of a
RAIDZ array)...
