The Seagate Exos X18 is a 3.5-inch enterprise hard drive with a 12 TB storage capacity, designed for data centers and large-scale cloud storage solutions. It connects via a 12 Gbit/s SAS interface, which provides the bandwidth required for high-availability server and storage systems. This drive is engineered for bulk data applications and is optimized for sustained, 24/7 workloads. Its construction supports reliable operation within demanding enterprise environments.
Performance is delivered through a 7200 RPM spindle speed and a 256 MB cache, which work together to manage data-intensive tasks efficiently. To ensure operational stability in dense multi-drive enclosures, the drive includes rotational vibration sensors that mitigate interference from adjacent drives. It also incorporates end-to-end data protection to maintain data integrity throughout the storage process. A Mean Time Between Failures (MTBF) rating of 2.5 million hours establishes its suitability for continuous use.
