Shouldn't we be talking about RAID 15 here, rather than RAID 51 ?  I
interpret "RAID 15" to be like "RAID 10" - a raid5 set of raid1 mirrors,
while "RAID 51" would be a raid1 mirror of raid5 sets.  I am certain
that you mean a raid5 set of raid1 pairs - I just think you've got the
name wrong.

Now that you mention it, yes, RAID 15 would fit much better with
convention.  Not sure why I thought 51.  So it's RAID 15 from here.

For us casual readers & RAID users could you clarify RAID15? Would
that be a bunch of RAID1's grouped together in what appears to be a
RAID5 to the system?

Thanks,
