Reading, ‘riting, and redundancy



Which of these RAID types splits data evenly across two or more disks, but does not provide any data redundancy?

A) RAID 0

B) RAID 1

C) RAID 5

D) RAID 1+0

E) If it’s not redundant, why is there an R?


The answer: A) RAID 0

RAID 0 separates data and splits it across multiple disks. While this provides some speed advantages, any drive failure breaks the entire array and user data would be lost.
