 AFAIK you can't RAID1 more than two drives, so the above doesn't make

Yeah, I've never seen a way to RAID-1 more than 2 drives either.  It
would have to be his first one:

D1 + D2 = MD0 (RAID 1)
D3 + D4 = MD1 ...
D5 + D6 = MD2 ...
MD0 + MD1 + MD2 = MDF (RAID 0)


I don't know what the failure mode ends up being, but on linux I had no problems creating what appears to be a massively redundant (but small) array

md0 : active raid1 sdo1[10](S) sdn1[8] sdm1[7] sdl1[6] sdk1[5] sdj1[4] sdi1[3] 
sdh1[2] sdg1[9] sdf1[1] sde1[11](S) sdd1[0]
      896 blocks [10/10] [UUUUUUUUUU]
