Although you might be knowledgeable about RAID systems and their various implementations. RAID stands for Redundant Array of Independent Disks. It is some disks that come together and have the capacity to replicate and divide data through the entire set. The main benefit is that among the discs in the set can fail, but the remaining drives in the set can continue unaffected. Which means that important computer data is still safe and you can even carry on working in most cases.
Despite this fault tolerance, even these complex fault-tolerant RAID systems can occasionally crash and become inaccessible. Specifically, a few of the issues that can adversely affect the RAID system can range from controller failures, multiple drive failure, accidental replacement of media components, accidental format, lost array configuration, RAID degradation from intermittent disk failure, etc.
