I hadn't seen these before - they look attractive.

I am not sure the review says "Can’t use in RAID arrays". What it does
say is that the write performance is somewhat non-deterministic and so
in some RAID configurations (anything with a checksum disk), performance
will be bad, especially during re-build.

On the other hand, striped and linear RAID shouldn't be a problem. I'm
guessing that pure mirrored RAID shouldn't be too much of a problem.

RAID-5, -6 and -10 is likely to have poor performance, but it will
still work, from what I understand.
