You are in the process of configuring a RAID array of disks and want to know by the Certkiller administrator which of the following RAID arrays will let the interleaving of read and write sectors between the multiple drives?
A.
RAID 6
B.
RAID 5
C.
RAID 0
D.
RAID 3
Explanation:
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 6 implementation uses independent data disk arrays with two distributed parity blocks and it then stripes blocks of data and parity across an array of drives similar to RAID 5 where two sets of parity information for each parcel of data, requiring two drives to do so.
B: RAID 5 is used to distributes its parity blocks among its independent data disks.
D: The RAID 3 specification is designed to use parallel transfers similar to RAID 2, along with byte-level parity striping.
