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.
