RAID 5 set
An array type that is similar to a stripe set in that it stripes data
evenly across its respective drives in equal-sized chunks, except that
it uses parity to provide redundancy. A RAID 5 set must be made up
of at least three equal-sized partitions on different drives. You must
have at least three partitions to permit the system to rebuild the data
if one drive fails. As data is s triped across the partitions, one chunk
of each stripe is used for parity data. See also chunk; partition;
parity.
redundancy
The capability of preventing data loss if a drive fails. Some array
types give you this capability using one of two methods: two
identical copies or parity.
