In RAID 10 would it matter that WALL is in the same RAID set?
Would it be better:
4 disks in RAID10 Data
2 disks RAID 1 WALL
2 hot spares
I guess the first question is why 2 hot spares? You don't have many
spindles, so you don't want to waste them. It might turn out that a
larger array with more spindles with outperform a smaller one with
fewer, regardless of RAID level (assuming a decent battery-backed
cache). You might try
5 RAID5
2 RAID1
1 spare
