RAID 4 no relation data striping
RAID 5
RAID 5 consists of block-level striping with distributed parity. Unlike in RAID 4, parity information is distributed among the drives. It requires that all drives but one be present to operate. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost. RAID 5 requires at least three disks.There are many layouts of data and parity in a RAID 5 disk drive array depending upon the sequence of writing across the disks, that is:
