Yes, both are striped across the backend.  However when performing random IO to a striped meta volume, you are very likely to have more than one volume with active IO, and with a concat meta only one volume is likely to be active.  The difference in performance comes from the volume being able to do IO to and from cache, and has nothing to do with the backend at all.
