Detailed explanation-1: -RAID 6 offers very high fault-and drive-failure tolerance and can be used for environments that need long Data retention periods, such as archiving. RAID 6 uses less storage than, for example, a RAID 10 array, which can only store half of its total storage capacity in data, as the other half is used by mirroring.
Detailed explanation-2: -RAID – or Redundant Array of Independent Disks – is a type of storage that writes data across multiple drives within the same system. Different configurations are expressed as numbers, such as RAID 0, RAID 1, or RAID 5.
Detailed explanation-3: -RAID 0 (also known as a stripe set or striped volume) splits ("stripes") data evenly across two or more disks, without parity information, redundancy, or fault tolerance.
