RAID 11. Because 11 is more than 10.
(RAID "10" is really RAID 1+0)
Raid 11 is just an extra notch on the dial that doesn't actually do anything.
Why not just have raid 10 do the same as 11 and then you wouldn't need it!
There's a technical explanation for it on Spinal Tap The Movie. I'm afraid it's over my head though.
Yeah, but 11 is more than 10.
