RAID 5 requires at least three drives and distributes parity information across all drives to provide fault tolerance, while still improving read and write speeds.
This statement is incorrect.
This statement is correct.
RAID 5 improves read and write speeds by striping the data across multiple drives and provides fault tolerance by distributing parity information across all the drives in the array. Parity is a method used to recreate any data lost when a single drive fails. Understanding that RAID 5 requires a minimum of three drives is crucial, as with fewer than three drives, parity cannot be distributed effectively and the RAID 5 functionality cannot be achieved. Subsequently, if any one drive fails, the data can be reconstructed from the remaining drives using the parity information. RAID 0 stripes data without parity contributing to speed but offers no fault tolerance, RAID 1 creates a mirror of data, providing fault tolerance with no significant speed improvement, and RAID 10 combines features of RAID 0 and RAID 1 and requires a minimum of four drives.
