What is the characteristic of RAID 5 regarding data recovery?

RAID 5 is designed to provide a balance between performance, storage efficiency, and data redundancy. One of its key characteristics is the way it utilizes parity for data recovery. Specifically, RAID 5 creates a parity block alongside the data blocks, which allows the array to reconstruct lost data in the event of a single drive failure. This means that if one drive fails, the information from the remaining drives can be used in conjunction with the parity data to recover the lost information.

The ability to re-create data from a single drive failure using parity is a fundamental feature of RAID 5, contributing to its effectiveness in maintaining data integrity and availability. If a drive within a RAID 5 array fails, operations can continue without interruption, and the lost data can be restored as long as only one drive is affected. This level of fault tolerance makes RAID 5 a popular choice for many businesses requiring reliable data storage.

While RAID 5 is effective against single drive failures, it is important to note that it cannot recover from multiple drive failures, hence the other options do not correctly reflect the capabilities or limitations of RAID 5.
