Why each option
RAID 1 offers data redundancy by mirroring data across two drives, meeting the requirement for redundancy with the fewest drives possible.
RAID 0 stripes data without providing any redundancy.
RAID 1 mirrors data across two physical drives, ensuring data redundancy by having an exact duplicate. This configuration only requires a minimum of two drives to provide fault tolerance against a single drive failure.
RAID 5 requires a minimum of three drives to provide redundancy using parity.
RAID 10 combines mirroring and striping, requiring a minimum of four drives for redundancy.
