Seagate Exos X20 18TB SATA Enterprise Hard Drive (Renewed)

The Seagate Exos X20 18TB SATA Enterprise Hard Drive is engineered for the demanding requirements of hyperscale and cloud data center environments. Built on Seagate's proven helium side-sealing weld technology, the drive packs 18 terabytes into a standard 3.5-inch form factor while running cooler and consuming less power than traditional air-filled drives. The 7200 RPM spindle speed paired with enhanced caching delivers consistent throughput tuned for large sequential data transfers, while the SATA 6Gb/s interface ensures broad compatibility with existing server and storage infrastructure.

Reliability is central to the Exos X20's design. The drive carries a 2.5 million hour MTBF rating—an enterprise benchmark that reflects its suitability for always-on, write-intensive workloads. Digital environmental sensors continuously monitor internal conditions such as temperature and humidity, providing an additional layer of operational intelligence for storage administrators. As a renewed unit, this drive has been professionally inspected and tested to meet functional standards, offering the same Exos X20 technology trusted by the world's leading cloud service providers at a reduced price point. It is a practical choice for expanding NAS arrays, populating storage servers, or any application where high-capacity, reliable spinning storage is needed.
