Which RAID level is described as mirroring multiple drives as clones of each other?

RAID 0
RAID 1
RAID 5
RAID 10

The correct answer is: RAID 1

The correct answer is indeed RAID 1, as this RAID level is specifically designed for mirroring, where data is duplicated across two or more drives. This means that each drive contains an exact copy (or clone) of the data, providing redundancy. If one drive fails, the data remains safe and accessible on the other drive(s). This dual integrity ensures high availability of data, making RAID 1 a common choice for critical systems requiring fault tolerance. In contrast, RAID 0 stripes data across multiple drives without any redundancy, improving performance but offering no protection against drive failures. RAID 5 utilizes striping with parity, allowing for data recovery from a single drive failure but also does not involve complete mirroring. RAID 10 combines mirroring and striping, offering redundancy and performance but is not solely defined by mirroring alone like RAID 1 is.
