How many minimum drives are required to create R5 (RAID 5)?

technology storage

  1. 1

  2. 3

  3. 5

  4. 7

Show answer
Correct Option: B

AI Explanation

To create a RAID 5 configuration, a minimum of three drives is required.

In RAID 5, data is striped across multiple drives with parity information distributed among the drives. This provides fault tolerance, as the parity information allows for the reconstruction of data in case of a drive failure. Each drive in the RAID 5 array stores both data and parity information.

To ensure redundancy and fault tolerance, RAID 5 requires at least three drives. This way, if one drive fails, the data can still be reconstructed using the parity information on the remaining drives.

Therefore, the correct answer is B) 3.
