Um.... for what it is worth, I just ran "vol status -r" on an F85 - looks like RAID4 to me!

f85-rtp> vol status -r Volume vol0 (root)

RAID group 0

Finally, does the F85 really use RAID 0? If so, it's true that it's not as failure proof, but then if the model was designed for RAID 0, then it's simply not targeted at the same market as a redundant RAID unit. If capacity and performance are far more important to you then redundancy, then RAID 0 is the way to go. (Though as I said, I'd be surprised if it really was RAID 0. If it's not, then a blatant lie like that would immediately turn me off to any vendor.)

Since nobody else has responded..I'll step in.

The F85 enjoys the FULL and complete feature set of WAFL and its engineering around RAID4 to do its work quickly, quietly, and with outstanding performance compared to any other filesystem or features the competition can throw at us.
