Be careful when talking about RAID controllers in general. They are
not created equal! ...
Hardware raid controllers have done the job for many years ...
Not quite the same job as ZFS, which offers integrity guarantees that
RAID subsystems cannot.
I'm a
little bit concerned about the new message (from some) out there that
they are " no good " anymore. Given the code on those controllers are
probably not as elegant as zfs ... and given my personal preference of
"being in control", I cannot dismiss the fact that some of these
storage units are fast as hell, ...
"Being in control" may mean *avoiding* black box RAID hardware in
favour of inspectable & maintainable open source software, which was
the earlier poster's point.
