The data capacity RAID 10 logical drive equals the capacity of the smallest physical drive times the number of
physical drives, divided by two.
In some cases, RAID 10 offers double fault tolerance, depending on which physical drives fail.
RAID 10 arrays require an even number of physical drives and a minimum of four.
For RAID 10 characteristics using an odd number of physical drives, choose RAID 1E.
