The RAID (Redundant Array of Independent Disks) configurations are used to combine multiple physical hard drives into one logical volume to achieve various goals, such as increased performance, fault tolerance, or a combination of both.
The security administrator needs a RAID configuration that prioritizes high read speeds and fault tolerance. Since multiple drive failures are unlikely, the administrator can choose a RAID level that provides a balance between performance and redundancy.
Here is a brief description of the RAID configurations mentioned in the question:
A. RAID 0: This configuration stripes data across multiple disks without redundancy. It offers high read and write speeds since data is split between multiple drives, but it does not provide any fault tolerance. If one disk fails, all data on the RAID array is lost.
B. RAID 1: This configuration mirrors data between two disks. All data is written to both disks simultaneously, providing fault tolerance. However, it does not provide any performance benefits since all data must be written twice.
C. RAID 5: This configuration stripes data across multiple disks and uses parity information to provide fault tolerance. If one disk fails, the missing data can be reconstructed using the parity information on the remaining disks. It offers a balance between performance and redundancy.
D. RAID 10: This configuration combines RAID 1 and RAID 0. It mirrors data between two sets of striped disks, providing both high read speeds and fault tolerance. It requires at least four disks and can tolerate the failure of one disk in each set.
Given the requirements, the security administrator should choose RAID 10. It provides both high read speeds and fault tolerance and can tolerate the failure of one disk in each set. While RAID 5 also offers fault tolerance and performance benefits, it is less reliable than RAID 10 since a second disk failure during a rebuild operation can result in data loss.
Therefore, the correct answer is D. RAID 10.
