1

Name RAID 0?

Striping

2

Redundancy of RAID 0?

0. RAID 0 has 0 redundancy.

3

Minimum disks required for RAID 0?

2

4

Explain RAID 0

The data stored is split between 2 or more physical drives

5

Performance of RAID 0

Data is written quickly as it is split over multiple drives

6

Name RAID 1

Mirroring

7

Redundancy of RAID 1

Array will still work as long as one drive is operational

8

Minimum disks require for RAID 1?

2

9

Explain RAID 1

The data stored is duplicated to 2 or more physical drives

10

Performance of RAID 1

High disk usage as files are duplicated on multiple drives.

11

Name RAID 5

Striping with Parity

12

Redundancy of RAID 5

Needs all but 1 drive operational

13

Minimum disks required for RAID 5

3

14

Explain RAID 5

File blocks are striped, along with a parity block.

15

Performance of RAID 5

Efficient use of disk space. Files are not duplicated, but space is still used for parity

16

Name RAID 10 (1+0)

A Stripe of Mirrors

17

Redundancy of RAID 10

Can loose all but one of each set of mirrors

18

Minimum disks required for RAID 10

4

19

Explain RAID 10

2 pairs are mirrored and then striped with the other

20

Performance of RAID 10

The speed of striping with the redundancy of mirroring

21

What is a RAID

Redundant Array of Independent Disks
