NO! The CERN study does not mention ZFS at all! So, I did not claim
superiority of ZFS (although it is! And, now I'm doing it!), I simply wanted
to STATE that RAID in Hardware alone is NOT SUFFICIENT. The study is still
valid! But it's NOT about RAID-Controlers alone! You did start the fight on
(defending of) RAID-controlers, not me!

Agreed!
BUT: With, for example ZFS, there no longer is a need for HW
RAID-controlers...
