 RAID Level-5

RAID level-5 requires a minimum of three hard disk drives. This
RAID level stripes data and parity across all drives in the array.
When an array is assigned RAID level-5, the capacity of the logical
drive is reduced by one drive (for data-parity storage).

RAID level-5 is generally the most desirable choice, because it offers
both data protection and increased throughput. RAID level-5 gives
you higher capacity than RAID level-1, but RAID level-1 offers better
performance.

The following illustration shows data arranged in an array with three
hard disk drives. The logical drive is assigned RAID level-5. Notice
that the storage of the data parity also is striped, and it shifts from
drive to drive.
