BACKGROUND In a RAID 5 array, one stripe unit per stripe is allocated to hold the parity for the stripe where the parity is equal to the XOR'd value of all the other stripe units in the stripe. A sample 5-drive RAID 5 array may look as follows: Drive 1 Drive 2 Drive 3 Drive 4 Drive 5 Stripe 1 D1 D2 D3 D4 P1 Stripe 2 D5 D6 D7 P2 D8 Stripe 3 D9 D10 P3 D11 D12 .
