Question

Explanation
RAID 5 is a RAID level that provides striping with parity, which means that data is distributed across all disks with one disk storing parity information for error correction. RAID 5 can tolerate one disk failure without losing data. RAID 5 provides the most storage as well as disk redundancy out of the four RAID levels given, since it only uses one disk for parity and the rest for data. For example, if four 200GB drives are used in a RAID 5 array, the total storage capacity would be 600GB (200GB x 3), while in RAID 0 it would be 800GB (200GB x 4), in RAID 1 it would be 200GB (200GB x 1), and in RAID 10 it would be 400GB (200GB x 2).
