Any controller that claims RAID10 on a server with 6 drive bays should be able to put all six drives in an array. But you'll get a three-way stripe (better performance) instead of a three-way mirror (better fault tolerance). So, A B C A B C and not, A B A B A B The former gives you more space but slightly less fault tolerance than four drives with a hot spare.
