I installed 6 hard drives on X8DAI motherboard and plan to create raid 10 with Intel RAID on ICH10R raid controller. But the Intel Raid utility does not allow me to do it, only allows creating raid 10 with 4 hard drives. Why?
It is the limitation of the ICH10R raid controller. Please refer to link below.
