[Gluster-users] To RAID or not to RAID...

After reading RedHat documentation regarding optimizing Gluster storage
another question comes to my mind:
Let's presume that I want to go the distributed dispersed volume way.
Three nodes which two bricks each.
According to RedHat's recommendation, I should use RAID6 as underlying
RAID for my planned workload.
I am frightened by that "waste" of disks in such a case:
When each brick is a RAID6, I would "loose" two disks per brick - 12
lossed disks in total.
In addition to this, distributed dispersed volume adds another layer of
lossed disk space.
Am I wrong here? Maybe I didn't understand the recommendations wrong?
