What is the disk fault tolerance in a minimally sized RAID 50 array?

EXPLANATION

RAID 50, also called RAID 5+0, combines the straight block-level striping of RAID 0 with the distributed parity of RAID 5. As a RAID 0 array striped across RAID 5 elements, maximum fault tolerance is 1 in each RAID 5. Then the maximum fault tolerance is 2.
