What happens if a disk fails in RAID 10?
In this article we'll talk about what happens if a disk fails in RAID 10? RAID 10 requires at least four disks to function. The disks are divided into two groups, each with two disks. The data is mirrored between the two disks in each group, and then the striped data is written across the mirrored pairs. This configuration offers high performance and redundancy, but it also means that the failure of a single disk can have a significant impact on the data stored in the array.
