What RAID level is described as multiple drives acting as one single drive with zero redundancy?

RAID 0
RAID 1
RAID 5
RAID 10

The correct answer is: RAID 0

RAID 0 is the correct answer because it is the only RAID level among the options that does not offer any redundancy. RAID 1, RAID 5, and RAID 10 all provide some form of redundancy through mirroring, striping, or a combination of both. RAID 0, on the other hand, uses striping without any mirroring, meaning that there is no backup or fault tolerance for data. This makes RAID 0 a high performance option, but also very vulnerable to data loss in case of drive failure. Therefore, RAID 0 is described as multiple drives acting as one single drive with zero redundancy. In contrast, the other options typically involve multiple drives providing some form of backup or fault tolerance for data.
