Software is more flexible than that. It works with partitions.

Of course, for redundancy purposes, you want to mirror partitions on
separate physical drives. But you don't have to mirror all the
partitions on all your drives.

For example, you don't raid swap partitions. Or you may want to have a
small /boot that's not raid. And then a big /home which is mirrored.
