A key feature of a Storage Area Network (SAN) is its use of block-level storage, which provides greater efficiency for high-performance applications. In a SAN, data is stored in blocks rather than files, allowing servers to access storage volumes directly over a network without the need for a file system in between. This block-level storage architecture is particularly beneficial for situations that require rapid access to large amounts of data, such as databases and virtualization environments.

By bypassing traditional file protocols, SANs can also minimize latency and optimize performance, making them more suitable for enterprise environments that demand continuous access to critical applications and services. This characteristic sets SANs apart from other storage solutions that may rely on file-level storage, which can introduce additional overhead and limit scalability.

This understanding helps highlight the operational advantages of using a SAN, especially in contexts where speed and reliability of data access are essential for maintaining business operations.
