Question

What is the stripe size of a five-disk RAID 5 set with a strip size of 16KB? Compare it with the stripe size of a five-disk RAID 0 array with the same strip size.

a) 16KB for RAID 5, 80KB for RAID 0
b) 80KB for RAID 5, 16KB for RAID 0
c) 16KB for both RAID 5 and RAID 0
d) 80KB for both RAID 5 and RAID 0

Answer 1

The stripe size of a five-disk RAID 5 set with a strip size of 16KB is 64KB, while the stripe size of a five-disk RAID 0 array with the same strip size is 80KB.

Step-by-step explanation:

The stripe size of a five-disk RAID 5 set with a strip size of 16KB can be calculated by multiplying the number of data disks in the set by the strip size. In this case, the stripe size would be 16KB x (5-1) = 64KB. Comparing this with a five-disk RAID 0 array with the same strip size, the stripe size would also be 16KB x (5) = 80KB.
