Question 1

striping

Answer 1

dividing body of data into blocks and spreading across storage devices

Question 2

parity

Answer 2

rebuild data if drive fails, guards against data loss in up to two failed drives - slow and expensive but safe

Question 3

disk mirroring

Answer 3

replication of logical disk volumes onto separate physical hard disks - continuous availability

Question 4

RAID 0

Answer 4

Striping
at least 2 disks

Ideal Use (optional): non-critical storage of data that has to be read at high speed, such as on a video/audio editing station or gaming environments

Question 5

RAID 1

Answer 5

Mirroring
at least two disks
higher cost

Ideal Use (optional): critical data storage environments such as standard application servers or systems where high data redundancy, reliability (availability), and performance is needed

Question 6

RAID 5

Answer 6

Striping with parity
At least three drives
Most efficient use of drive space

Ideal Use (optional): file storage and application servers such as email, general storage servers, news servers, etc.

Question 7

RAID 6

Answer 7

Striping with double parity
At least four drives

Requires a minimum of four disks.
Single drive failure results in in reduced performance for whole array.

Ideal Use (optional): Office automation, online customer service, and applications that require very high availability. Can be used for applications with high read request rates, but lower write requests.
