No, "nodatasum" will prevent newly-written data from being checksummed. However, if a checksum already exists (because the data was written to a filesystem mounted without the "nodatasum" option), btrfs will still verify the checksum, regardless of the current setting of nodatasum. There is currently no way of preventing btrfs from verifying checksums if they exist; I don't believe that there's any way of removing an existing checksum, either.
