Seagate Exos X18 14TB 3.5" 7200RPM SATA Internal Hard Drive

The Seagate ST14000NM001J is a 14 TB 3.5-inch hard drive from the Exos X18 line, built for administrators who need dependable, high-capacity storage inside servers, JBOD enclosures, or cloud nodes. It connects through a SATA 6 Gb/s interface, so it drops straight into standard backplanes without special adapters or cabling.

Inside the drive, platters spin at 7200 RPM and work with a 256 MB cache and conventional magnetic recording. This combination can sustain up to 270 MB/s on sequential reads and 258 MB/s on writes, giving backup windows, analytics jobs, and large file transfers the speed they demand.

A helium-sealed housing keeps air turbulence low, which in turn cuts power draw and allows more drives to live peacefully in a dense rack. Less heat and vibration mean you can stack chassis after chassis without worrying about wasted energy or premature failures.

Seagate Secure hardware-level encryption protects data at rest, while a 5-year limited warranty adds the long-term reassurance enterprise budgets require. Whether you are growing a private cloud, refreshing a video surveillance archive, or expanding cold-storage tiers for compliance data, this Exos model delivers the capacity and resilience that keep critical information online and ready.
