Operations Manual
7.1.1 RAID Level 5
RAID Level 5 maps the data across the drives and stores parity information for each data stripe on different drives in the array. The parity data, labeled P in Figure , is distributed. This lessens the data congestion that occurs if all of the parity data is written to one drive. A RAID 5 array can preserve data if one drive fails. However, if two drives fail, all data in the array is lost.
