You have four HDDs that are 2 TB each. You need to configure the drives so that you have fault tolerance and at least 6 TB of usable disk space. How should you configure the drives?

RAID 5 offers both fault tolerance and maximizes storage efficiency by distributing parity information across all the drives. With four 2 TB drives, RAID 5 will provide 6 TB of usable space (since one drive's capacity is used for parity), meeting the requirement. RAID 0 offers no fault tolerance, mirrored volume (RAID 1) would only provide 4 TB of usable space, and a spanned volume offers no fault tolerance.
