Seagate Exos X18 14TB 3.5" 7200RPM SAS III 12 Gb/s Internal HDD

The Seagate ST14000NM004J is a 14 TB internal hard drive built for organizations that move and store data at scale. It fits into any system with a 3.5-inch bay and a SAS backplane, delivering sustained transfer rates up to 270 MB/s through a 12 Gb/s interface. A spindle speed of 7200 rpm keeps latency predictable, so large data sets stream smoothly whether you are backing up virtual machines or feeding analytics platforms.

Inside the helium-sealed enclosure, Seagate uses PowerBalance technology to tune power draw against throughput, helping data center teams lower energy costs without sacrificing performance. Integrated digital sensors track temperature and vibration in real time, supporting tighter control over environmental conditions and extending component life. The result is a mean time between failures of 2.5 million hours and the confidence that comes with a five-year limited warranty.

This drive feels at home in hyperscale racks, cloud storage nodes, and enterprise RAID arrays that run around the clock. IT administrators can deploy it in high-density enclosures for object storage, content delivery networks, or large tape-replacement archives. System integrators who design backup targets or tier-two storage pools will appreciate the generous 256 MB cache, which cushions bursts of random traffic during peak access windows.

Whether you manage a rapidly growing SaaS platform or maintain on-premises infrastructure for video surveillance, the Exos X18 family delivers capacity, speed, and reliability in a single product that keeps expanding datasets online and readily available.
