SK0-005 · Question #219
A technician needs to configure a server's RAID array for maximum capacity. Which of the following RAID levels BEST meets this requirement?
The correct answer is A. 0. RAID 0 (striping) provides the highest storage capacity among standard RAID levels because it utilizes 100% of the combined disk space for data without any redundancy overhead.

Why each option
RAID 0 (striping) provides the highest storage capacity among standard RAID levels because it utilizes 100% of the combined disk space for data without any redundancy overhead.
RAID 0, also known as striping, combines multiple hard drives into a single logical unit without implementing any redundancy or parity. This configuration allows all disk space across the array to be used for data storage, resulting in the maximum possible capacity from the installed drives.
RAID 1 (mirroring) duplicates all data across two disks, meaning only half of the total raw disk capacity is usable for storage.
RAID 5 dedicates the capacity of one disk in the array to store parity information, thereby reducing the total usable capacity by one drive.
RAID 6 dedicates the capacity of two disks in the array to store parity information, offering increased redundancy but further reducing total usable capacity compared to RAID 5 or RAID 0.
