Disk Array
A disk array is a data storage system that combines multiple physical disk drives into a single logical unit to provide improved performance, reliability, and capacity. It uses techniques like RAID (Redundant Array of Independent Disks) to distribute data across drives, enabling features such as data redundancy, faster access speeds, and easier management. Disk arrays are commonly used in servers, data centers, and enterprise storage environments to ensure data availability and integrity.
Developers should learn about disk arrays when working on systems requiring high data availability, performance, or large-scale storage, such as database servers, cloud infrastructure, or backup solutions. They are essential for implementing RAID configurations to prevent data loss from drive failures and to optimize I/O operations in applications handling heavy read/write loads, like transactional databases or media streaming services.
