To achieve maximum capacity in a RAID array, which RAID level should be used?

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

Answer: (B)

RAID 0 is designed to achieve maximum capacity in a RAID array by utilizing a technique known as striping. In this configuration, data is split evenly across two or more drives, which means that the combined storage capacity of the array is the sum of the individual drives. For example, if two 1TB drives are combined in a RAID 0 setup, the total usable capacity will be 2TB. This approach maximizes the storage potential since there is no redundancy or parity information being stored, which means all available disk space contributes directly to the usable capacity. While RAID 0 enhances performance and utilization, it does come with the risk that if one drive fails, all data in the array is lost, as there is no duplication of data. Other RAID levels, such as RAID 1, RAID 5, and RAID 10, offer redundancy and fault tolerance but do so at the cost of available storage capacity. In RAID 1, mirror copies take up half the space. RAID 5 uses parity information, which reduces usable capacity, and RAID 10, which combines mirroring and striping, also limits the available space since half is used for redundancy. Therefore, if the goal is to achieve maximum capacity in a
