What advantage do hot-swappable drives provide in a server environment?

Hot-swappable drives offer the significant advantage of being replaced without the need to shut down the server. This capability is crucial in server environments that require high availability and minimal downtime. When a drive fails, system administrators can quickly replace it with a new one while the server continues to run and provide services without interruption. This feature enhances operational efficiency and reliability, especially in critical applications where every moment of downtime can lead to productivity losses and impact service delivery.

Other options, while they may describe important aspects of server performance or capabilities, do not pertain to the core benefit of hot-swappable drives, which is the seamless replacement of hardware without disrupting server operations.
