Seagate ST12000NM002G 12TB 12Gb/s SAS HDD

Enterprise-Grade Storage for Data Centers and High-Capacity RAID

The Seagate ST12000NM002G Exos X16 12TB SAS Hard Drive is a high-performance enterprise drive designed to deliver maximum storage capacity and the highest rack space efficiency. As the flagship of the Seagate X class, the Exos X16 is built for demanding data environments, including hyperscale applications, big data analytics, and high-capacity RAID storage, making it a strong fit for engineering workstations, network servers, mainframes, and supercomputers that require continuous 24/7 operation.

Built for Rack-Space Efficiency and Low Total Cost of Ownership

This drive is made for data centers that need to maximize storage capacity while minimizing power draw and physical footprint. Its next-generation helium-sealed design with side-sealing weld technology reduces power consumption and weight compared to air-filled drives, helping data centers meet stringent total cost of ownership requirements while adding handling robustness during installation. Digital environmental sensors continuously monitor internal drive conditions to help maintain optimal performance throughout the drive's service life.

Fast, Reliable Dual-Port SAS Performance

The Exos X16 features a dual-port SAS 12Gb/s interface, delivering professional-grade throughput, data path redundancy, and seamless integration into enterprise server environments. Operating at 7200 RPM with a 256MB cache, the drive achieves sustained data transfer rates of up to 261 MB/s for responsive data access, with an average latency of 4.16ms. It carries a 2.5-million-hour MTBF rating and a workload limit of 550TB per year, reflecting the reliability standard expected of Seagate's enterprise-class drives for continuous, heavy-duty use.

Built-In Data Security

The drive includes Seagate Secure technology, supporting safe and easy drive retirement at end of life, an important consideration for IT departments managing large storage fleets and needing to securely decommission hardware.
