Is

        :dt=RAID:se#512:ns#62:nt#64:sc#3968:nc#22699:\

much better than

        :dt=RAID:se#512:ns#62:nt#16:sc#992:nc#90796:\

or should I relabel and format my RAID1 before populating it with real data?
I won't be able to do that again too easily after putting some 20 GB of data
on the disk..
