Show answer & explanation
Correct answer: A, B
Correct answers: Fault-tolerance and High speed.
RAID stands for Redundant Array of Independent Disks. RAID stores data across multiple disks. Redundancy/parity/mirroring in RAID levels such as RAID 1, 5, and 6 provides fault tolerance. Striping in RAID levels such as RAID 0 and many combined RAID levels can improve read/write throughput, giving high speed.
RAID is not primarily used to provide high data density; redundancy can even reduce usable capacity. Therefore, options A and B are correct.
