Given an array with sixteen 300GB drives, a storage administrator needs to know how much raw usable space can be made available while still maintaining a highly available RAID configuration with two h

RAID 1 mirroring with 14 drives would result in 7 mirrored pairs, yielding (14/2) * 300GB = 2.1TB usable space, which is less than RAID 5.

RAID 6 with 14 drives (N-2 parity) would yield (14-2) * 300GB = 12 * 300GB = 3.6TB usable space, which is less than RAID 5.

With 14 drives remaining for the RAID array (16 total - 2 hot spares), RAID 5 uses N-1 drives for data and one for parity. This configuration provides (14-1) * 300GB = 13 * 300GB = 3900GB, or 3.9TB, and is considered highly available.

RAID 0 provides no redundancy and is not considered highly available, failing a key requirement of the question, and even then, 14 drives in RAID 0 would yield 4.2TB, not 4.8TB.
