Which RAID level provides high-speed data access and maximum storage capacity?

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 6

Answer: (A)

RAID 0 is designed for high-speed data access and maximizing storage capacity. This RAID level achieves these goals by striping data across multiple disks without any redundancy. By distributing the data evenly, RAID 0 enhances read and write performance as multiple disks can be accessed simultaneously, resulting in faster data retrieval and storage. In terms of capacity, RAID 0 uses the entire capacity of the disks added to the array, meaning there is no overhead for parity or mirroring. As such, if you have multiple drives, the total usable storage capacity is equal to the sum of all drives. However, while RAID 0 offers these benefits, it lacks any form of fault tolerance, meaning that if one disk fails, all data in the RAID 0 array is lost. This characteristic makes it ideal for scenarios where performance and capacity are prioritized over data redundancy.
