Explanation
RAID 6 is a level of RAID that can survive the failure of two drives without the loss of data. RAID 6 uses block-level striping with two parity blocks distributed across all member disks. RAID 6 can tolerate two simultaneous drive failures and still provide data access and redundancy. RAID 0 is a level of RAID that uses striping without parity or mirroring, and offers no fault tolerance. RAID 0 cannot survive any drive failure without data loss. RAID 1 is a level of RAID that uses mirroring without parity or striping, and offers fault tolerance by duplicating data on two or more disks. RAID 1 can survive one drive failure without data loss, but not two. RAID 5 is a level of RAID that uses block- level striping with one parity block distributed across all member disks. RAID 5 can tolerate one drive failure without data loss, but not two.
