Isn't the advantage of having btrfs do all the raiding itself so one gets the checksums? If one puts btrfs on top of software or hardware raid, then if there is a checksum error, you don't have another copy of the data to fall back to. If one uses btrfs' raid1 or above for data and metadata, then you can suffer a checksum failure and get a good copy from another drive?
