I think that we must understand a bit better
systematic RS.

The ideal case would be to have a RAID system
where, while adding a disk, the user can decide
if it (the disk) would be for data extension or
for redundancy (parity) extension.

This should be always possible and, in the first
place, performance should not be the target.

As mentioned before, par2 does it without too
many issues, so I fail to see why three parities
should be the limit.

Actually, I'm trying to catch some RS expert in
order to get an explanation (Q&A) on how the
whole thing works. Unfortunately experts seem to
be quite sluggish... :-)
