Which of the following is a benefit of RAID configurations?

The choice highlighting increased data redundancy and performance is accurate because RAID configurations are specifically designed to enhance both the reliability and efficiency of data storage systems. In a RAID setup, data is distributed across multiple disks, which provides redundancy. This means if one disk fails, the data is still accessible from other disks, thereby minimizing the risk of data loss.

Additionally, many RAID levels (like RAID 0, RAID 1, RAID 5, and RAID 10) improve performance by allowing simultaneous read and write operations across different disks, which can significantly speed up data processing tasks. For example, RAID 0 stripes data across multiple disks to improve speed, while RAID 1 mirrors data to ensure redundancy. Overall, employing RAID configurations strategically combines both increased data security and enhanced access speed, making it a popular choice in various data-driven environments.
