The correct answer is RAID 6, which is specifically designed to provide striping with double parity. This configuration enhances data resilience and security by using two separate parity blocks to protect against data loss. In the event of a disk failure, RAID 6 can continue to operate normally because it can tolerate the failure of two disks simultaneously while still maintaining data integrity.

RAID 5, in contrast, uses only single parity and can only withstand one disk failure before data becomes vulnerable. RAID 10 combines mirroring and striping but does not utilize parity, which means it cannot provide the same level of fault tolerance as RAID 6. RAID 1 focuses strictly on mirroring data across multiple disks for redundancy but does not incorporate any striping or parity. Thus, RAID 6 stands out as the choice that uniquely offers both striping and the capability for robust data redundancy through double parity.
