What aspect of server performance does RAID typically enhance?

RAID, which stands for Redundant Array of Independent Disks, primarily enhances data availability through its various configurations. By distributing data across multiple disks, RAID can protect against data loss in the event of a drive failure. Different RAID levels provide varying degrees of redundancy and fault tolerance, ensuring that your data remains accessible even if one or more drives fail. This is crucial for businesses and applications that require high uptime and reliability.

While RAID configurations can also improve performance through increased read/write speeds due to parallel operations, the fundamental purpose revolves around maintaining data availability and integrity. In contrast, aspects such as power consumption, physical size of drives, and visual interface are not significantly impacted by the RAID system itself. Therefore, the enhancement of data availability is the most relevant aspect of RAID in relation to server performance.
