Seagate Exos X16 16TB 3.5" SATA III Enterprise Hard Drive

The Seagate Exos X16 is the flagship of Seagate's X-class enterprise lineup, engineered for hyperscale cloud datacenters and massive scale-out storage environments. This SATA III (6 Gb/s) variant delivers the highest capacity and performance in the Exos fleet, combining 16TB of storage, a 7200 RPM spindle, and a 256MB cache buffer tuned for large sequential data transfers and low latency at hyperscale.

Built with a helium-sealed design using next-generation side-sealing weld technology, the Exos X16 delivers lower power consumption (10W operating), reduced weight, and a lower total cost of ownership compared to air-filled drives. Digital environmental sensors monitor internal drive conditions in real time, while PowerBalance™ optimizes Watts/TB for maximum rack efficiency. Hot-plug capable with 512e/4Kn format flexibility, backed by a 2.5 million hour MTBF and 5-year warranty.
