RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure. It works by placing data on multiple disks and allowing input/output (I/O) operations to overlap in a balanced way, improving ...
