Which RAID configuration would not provide redundancy?

RAID 0 is specifically designed for performance and is known for striping data across multiple disks without any form of redundancy. In this configuration, data is divided into blocks and each block is written to a different disk. The primary advantage is improved read and write speeds, as multiple disks can be accessed simultaneously. However, because there is no mirroring or parity, if any single drive fails in a RAID 0 array, all data on the array is lost. Consequently, RAID 0 does not provide any redundancy to protect against disk failures, making it the only option that lacks redundancy among the listed RAID levels.
