RAID arrays are designed to allow one or two individual drives to fail without losing access to the data. Parity data is added to your data to enable data access even after drive failure(s).

The parity+data bits are spread across the drives. The smallest RAID arrays are 4 drives, but 6-8 drives in a RAID stripe is most common. With RAID 5, one drive's worth of capacity is dedicated to parity, while in RAID 6 two drive's worth are..."

The first crack in the edifice was the realization that if a drive failed in an array of multi-terabyte drives, the rebuild time was so long that the possibility of a second, terminal failure was too high. This led to a much more complex RAID 6, creating two parity records for each stripe..."
