What happens if a disk fails in a RAID 0 configuration?

In a RAID 0 configuration, data is split across multiple disks for improved performance and increased storage capacity. However, this setup does not provide any redundancy. When one disk fails, the data stored on that disk, as well as the data that was distributed across the other disks and dependent on the failed disk, becomes unrecoverable. As a result, the entire array is affected, leading to a complete loss of all data stored in that RAID 0 setup. This characteristic is critical to understand when considering RAID configurations, as RAID 0 can offer speed benefits but at the cost of data security. Consequently, data redundancy needs to be carefully considered when designing storage solutions if data integrity is a priority.
