Why each option
The question concerns setting up RAID with mirroring using two hard drives. RAID 1 is the specific RAID level that performs data mirroring to provide redundancy.
RAID 0, or striping, distributes data across multiple disks to improve performance but offers no redundancy or fault tolerance.
RAID 1, also known as mirroring, duplicates data identically across two or more disks, providing redundancy and fault tolerance. If one disk fails, the data remains accessible from its mirrored counterpart, ensuring data availability.
RAID 2 is a legacy RAID level that uses Hamming code for error correction with bit-level striping and is not primarily used for mirroring.
RAID 5 uses block-level striping with distributed parity, requiring at least three disks, and provides fault tolerance but is not data mirroring.
