A storage server is a type of computer server designed specifically for storing and managing large amounts of data. Unlike a standard file server, which simply provides a shared storage space for users to access and save files, a storage server is optimized for performance, scalability, and reliability.

Storage servers typically use high-capacity hard drives or solid-state drives (SSDs) to store data, and may also include redundant power supplies, cooling systems, and other features to ensure uptime and data protection. They may also use specialized RAID (redundant array of independent disks) configurations to increase performance and redundancy.

Storage servers are commonly used in business environments where large amounts of data need to be stored and accessed quickly and reliably. They may be used for applications such as data backup and recovery, video and audio streaming, content delivery, and archiving.
