Which RAID level should a server administrator choose to achieve the highest possible storage capacity?

• A. RAID 1
• B. RAID 5
• C. RAID 0
• D. RAID 10

Answer: (C)

The selection of RAID 0 is the best choice for achieving the highest possible storage capacity in a RAID configuration. This level of RAID does not offer any redundancy, meaning that all the disk space from the drives in the array is utilized for data storage. In RAID 0, data is striped across multiple disks, resulting in improved performance and maximizing the amount of available storage. For instance, if a server administrator has two 1 TB drives in a RAID 0 configuration, the total storage capacity becomes 2 TB, as none of the capacity is reserved for parity or mirroring. This characteristic of utilizing 100% of the drive space makes RAID 0 the optimal choice for maximizing capacity. In contrast, RAID 1, RAID 5, and RAID 10 involve redundancy measures that reduce the overall usable storage capacity. RAID 1 mirrors data across two drives, limiting the available storage to the size of a single drive. RAID 5 uses one drive's worth of space for parity, which also decreases the total capacity based on the number of drives in the array. RAID 10 combines the features of RAID 1 and RAID 0, requiring a minimum of four drives, where half of the total capacity is used for mirroring. Thus,
