The correct answer is A. RAID 0. Given the requirement for maximized read and write throughput without concern for fault tolerance, RAID 0 is the appropriate choice as it stripes data across multiple disks, enhancing performance.
Question
A storage technician must implement a RAID configuration on a new database server. The database is required to process a large number of parallel read and writes; therefore, the storage administrator must select the appropriate array to maximize both read and write throughput. There is no concern for storage fault tolerance, since the database server will be joined to an existing cluster. Which of the following should the storage administrator implement?
Options
- ARAID 0
- BRAID 1
- CRAID 5
- DRAID 6

Why each option
Given the requirement for maximized read and write throughput without concern for fault tolerance, RAID 0 is the appropriate choice as it stripes data across multiple disks, enhancing performance.
RAID 0, or striping, distributes data across multiple disks in parallel, significantly increasing both read and write throughput by allowing concurrent access to different parts of the data. The question explicitly states that fault tolerance is not a concern, making RAID 0 ideal for performance.
RAID 1 (mirroring) provides excellent read performance and fault tolerance but does not maximize write throughput by striping data across multiple disks.
RAID 5 (striping with parity) offers a balance of performance and fault tolerance but involves parity calculations that can impact write performance compared to RAID 0.
RAID 6 (striping with dual parity) provides even greater fault tolerance than RAID 5 but at the cost of reduced write performance due to more complex parity calculations.
