Seagate Exos X18 3.5" 18TB, 7200 RPM, 256MB, SAS Hard Drive, Enterprise

The Seagate Exos X18 is an 18 TB enterprise-class hard drive engineered for high-density storage applications. It utilizes a 3.5-inch form factor and a SAS 12Gb/s interface for integration into hyperscale data centers, servers, and network-attached storage (NAS) systems. Its construction is focused on providing consistent and scalable storage for large data archives and cloud-based infrastructures. This model is designed to support demanding workloads in multi-drive environments where capacity and reliability are primary considerations.

Performance is delivered through a 7200 RPM spindle speed and a 256 MB cache, enabling sustained data transfer rates of up to 270 MB/s. The drive incorporates features to maintain data integrity and operational stability, including end-to-end data protection and integrated rotational vibration sensors to mitigate performance degradation in chassis with multiple drives. A high Mean Time Between Failures (MTBF) rating indicates its suitability for continuous, 24/7 operation in professional storage systems.
