16
Q

3 characteristics of RAID 0

A

Known as disk striping, decreases reliability (any disk failure destroys array), and suitable for systems that need performance more than fault tolerance

17
Q

3 characteristics of RAID 1

A

Requires 2 drives, Improved reliability (redundant storage of data), referred to as disk mirroring

18
Q

(T or F) The term “Disk duplexing” refers to a more reliable RAID Level 1 configuration setup where each disk relies on its own hardware that controls the drive.

A

True

19
Q

2 characteristics of RAID 5

A

Requires at least 3 drives & offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be re-created by the remaining drives)

20
Q

Which of the following RAID array types has the highest disk overhead?

A

RAID Level 1

21
Q

RAID Level 10 requires a minimum of how many drives?

A

4 drives

22
Q

Which two RAID types refer to a nested (hybrid) RAID level?

A

RAID 1+0 & RAID 10
