Why each option
To improve read performance for a data partition using only two physical hard drives, the technician should select RAID 1.
RAID 1 (mirroring) copies data identically to two or more drives. This setup allows read requests to be fulfilled by either drive, potentially improving read performance, and provides fault tolerance since data is duplicated.
RAID 5 requires a minimum of three drives to implement striping with distributed parity.
RAID 6 requires a minimum of four drives to implement striping with dual distributed parity.
RAID 50 is a nested RAID level (RAID 5 striped with RAID 0) that requires a minimum of six drives (at least two sets of RAID 5).
