Hi Neil,
Are you suggesting I do this?
mdadm --create /dev/md0 --level=10 --raid-devices=2 \
--parity=f2 /dev/sdc1 /dev/sdd1
I just tried it and it appears dog slow - for example
hdparm -t /dev/md0 claims 18MB/s, and I see a similar
number in /proc/mdstat for resync speed.

ala RAID-0 (-offset overhead).
During reads the same RAID-0 code (+mirroring offset) could be used.
During writes though, this would imply delayed mirroring.
