Linux does have a specialized "raid10" class if you use md. See the manpage and other documentation for mdadm and of course double-check the device names you want, but this is what I have done in the past: # create the array mdadm -C /dev/md2 -l 10 -c 128 -n 4 /dev/sd[c-f] # add it to the config mdadm --examine --scan | grep md2 >> /etc/mdadm.conf JN
