Raid 5 is different from raid 6.... To say that there are times it's ok to
use RAID 5 and then say you use raid 6... well... doesn't really say
anything about raid 5.

Also, what controller are you using?
From what I gather, raid 6 is less common and fewer cards support it (areca
is one of them I believe).
