You require RAID-6 because...? If you want more fault tolerance or
better performance, RAID-10 makes a lot more sense to me than RAID-6,

Using RAID-6 with 4 disks does not make much sense, no.
(Using RAID-10 with 4 disks works great, however. Yes, the overhead
is greater, but the write performance is much better, and it would
seem like RAID-10 would result in you having a configuration that
fits into 2TB LUN limitation....)
