I did say depends on the guarantees, right? :-) My point is that all
hw raid systems are not created equally.

That's the whole point of ZFS's checksumming - It's end to end...

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.
Depend on the guarantees. Some RAID systems have built in block
checksumming.
