A RAID level that uses a combination of striping and parity to enhance the security of data storage. As with RAID 4, data is striped across the multiple component disks in the RAID at the block level. The difference between the two is that RAID 4 stores parity information on a dedicated disk, while RAID 5 distributes the parity information across all the disks in the array. With a RAID 5 system, the data will be able to survive the loss of any single disk in the RAID.
