Yes, this was the solution. I think it was a misunderstanding on my part and I got confused about the partitions and installation. Installing grub without specifying a device parameter added the config to the /boot-RAID and made GRUB on flash open it. I'm not sure whether I should also install grub to sda/sdb as well, because I've read that this can cause issues with grub-update for some reason. It's probably not necessary for this system, but might be needed if I need to install the drive in another one.
