RAID 1+0 could give him 27GB as well: one RAID 1 set across the 18GB
drives, and one RAID 1 set across the 9 GB drives; then RAID 0 (or I
suppose LVM) across those RAID 1 sets to get the full 27GB. As far as
I understand it, there's no requirement that all the disks in RAID 1+0
all be the same size. Though again, whether a hardware based chipset
will support that configuration depends on the implementation, but
software RAID under linux will allow this.
