Tricky question ;-)

It depends on the architecture you are using (check the output of
sysctl kern.rawpartition, if it is 2 think 'c', if 3 think 'd').

You have two options: partition the outer raid, e.g. by creating a partition
'a' of type raid on them - in that case: use /dev/raid0a (for example).

Or use the whole device raw (without any partitions): in that case use
/dev/raid0d (or raid0c, depending on above output).

The second method is easier, and if you do not want other things on the outer
raids, just use it.
