Correct Answer: A
RAID level 0, also known as striping, involves splitting data evenly across two or more disks without parity information, redundancy, or fault tolerance. This means that if one drive fails, the entire array fails, resulting in total data loss. RAID 0 is typically used to increase performance, as it allows for faster read and write operations by using multiple disks simultaneously. However, because it does not duplicate data across the disks, it does not provide any form of data redundancy1.
