Explanation

RAID 1 is a type of disk mirroring that creates an exact copy of data on two or more disks. This means that if one disk fails, the data is still available on the other disk. RAID 0, RAID 5, and RAID 6 are all types of disk striping that distribute data across multiple disks. This can improve performance, but it does not provide any redundancy.
