Statement 1: We have a RAID5 protected group of disks. The protection level increases if we add more disks to the group. Statement 2: With a RAID 10 set the number of disks must be greater than 8 to always survive a dual disk failure.

Question

Adding more disks to a RAID 5 group does not increase protection level; it increases capacity and performance but also increases the risk of failure. RAID 10 can survive a dual disk failure with as few as 4 disks, as long as the failures occur in different mirrored pairs.
