Any use for mkfs.btrfs -d raid5 -m raid1 ?

If I lose 2 drives on a raid5, -m raid1 should ensure I haven't lost my
metadate.
>From there, would I indeed have small files that would be stored entirely on
some of the drives that didn't go missing, and therefore I could recover
some data with 2 missing drives?

Or is it kind of pointless/waste of space?

Actually, would it make btrfs faster for metadata work since it can read
from n drives in parallel and get data just a bit faster, or is that mostly
negligeable?

Thanks,
Marc
