ANSWER:

For bios booting, you just need one raid partition on each disk, unless the disks are larger than 2 TiB, in which case you must use GPT instead of msdos partition tables. In that cause you have to create a 1 MiB bios_grub partition on each disk you want to install grub to ( preferably all of them ).

For EFI, you need to use GPT no matter the size of the disk, and create an EFI system partition and mount it in /boot/grub/efi.
