Match the following $:$

$\begin{array}{}  \text{a.} & \text{RAID 0} & \text{i.} & \text{Bit interleaved parity} \\ \text{b.} & \text{RAID 1} &  \text{ii.} & \text{Non redundant stripping} \\ \text{c.} & \text{RAID 2} & \text{iii.} & \text{Mirrored disks} \\ \text{d.} &\text{RAID 3} & \text{iv.} & \text{Error correcting codes} \\   \end{array}$

$\textbf{Codes:}$

  1. $\text{a-iv, b-i, c-ii, d-iii}$
  2. $\text{a-iii, b-iv, c-i, d-ii}$
  3. $\text{a-iii, b-i, c-iv, d-ii}$
  4. $\text{a-iii, b-ii, c-iv, d-i}$

ANSWER D

This table explains data distribution method for each RAID level.

It can help you to answer these type of questions in RAID :)

RAID 0

Striping

Data is distributed among all the disks as blocks, sectors, or some other unit.

RAID 1

Mirroring

Duplicate all data in another set of disks

RAID 2

Hamming Code

Strips are very small (single byte or word).

Error-correcting code is calculated for bits on data disk and stored in the corresponding bit positions on parity disks

RAID 3

Bit-interleaved parity

A simple parity bit (not error correcting) is computed for all the bits in the same position on the data disks and stored in same bit position of parity disk

RAID 4

Block-interleaved parity

Stripes are relatively large.

A parity strip is computed for all the strips in the same position on the data disks and stored in parity disk

RAID 5

Block-interleaved

distributed parity

Distributes the parity strips across all disks.

Most versatile RAID level

RAID 6

Block-interleaved dual distributed parity

Two different parity calculations are carried out

and stored in separate blocks on different disks.

P: EXOR and Q: Data check algorithm
