Disk arrays

A disk array is a setup that combines multiple hard drives or SSDs to work together, acting as a single system. This configuration improves performance, increases storage capacity, and provides data redundancy—meaning if one drive fails, data remains safe. Disk arrays are common in servers and data centers, enabling efficient data management and ensuring reliability. They can be configured in different ways, such as RAID, which balances speed and safety according to specific needs. Essentially, a disk array enhances how data is stored, accessed, and protected across multiple drives.
