Why each option
The question asks to identify a primary benefit of using RAID 1 configuration in a server environment.
Data striping is characteristic of RAID 0 and RAID 5, where data is split across multiple drives to improve performance, but RAID 1 focuses on mirroring for redundancy.
RAID 1 (Redundant Array of Independent Disks Level 1) is known as mirroring, where data is simultaneously written identically to two or more drives. This provides high data redundancy and fault tolerance, as the system can continue operating even if one drive fails.
Data spanning, like JBOD (Just a Bunch Of Disks), combines drives into a single logical volume without providing any redundancy or performance benefits beyond simple concatenation.
RAID 1 requires a minimum of two hard drives to create a mirrored set, as data is duplicated across them.
