Question

You're installing two new hard drives into your network attached storage device. Your director asks that they be put into a RAID solution that offers redundancy over performance. Which would you use?

a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10

Answer 1

d. RAID 6

Step-by-step explanation:

RAID is a data storage technology that combines multiple physical disk drive components into a single logical unit. The functions of RAID is to provide performance and redundancy.

RAID 0 provides data stripping but it does not offer data stripping.

RAID 1 increases performance to about 2x but it limits the disk capacity to about 50%

RAID 5 provides redundancy and increased perfomance but it is limited to small disk drive.

RAID 6 also provides redundancy but it slows performance

RAID 10 increases performance and data protection.

RAID 6 is the best drive that offers redundancy over performance.
