A.
RAID 4
B.
RAID 0
C.
RAID 2
D.
RAID 5

RAID 0 is the simplest level, and uses disk striping without parity thus it requires less time for disk access, but no redundancy or error correction is provided making this type of RAID solution only to be used when reliability is not vital.
Incorrect
Answers:
A: The RAID 4 implementation uses independent data disks along with a shared parity disk and the block level striping can be adjusted for different applications.
C: The RAID 2 implementation uses data striping with error recovery, and is designed for use where high data-transfer rates are required.
D: RAID 5 is used to distributes its parity blocks among its independent data disks.
