Seagate Exos X16 12TB 3.5" 7200RPM SATA III Internal HDD

The Seagate ST12000NM001G is a 12 TB internal hard drive created for situations where capacity, speed, and dependability all matter. Built in a 3.5-inch form factor, it links to your system through a SATA III 6 Gb/s interface and spins at 7200 rpm, giving you sustained transfer rates up to 245 MB per second for quick backups, large file archives, and high-volume data streams.

Reliability sits at the center of this drive’s design. A 2.5 million-hour mean time between failures and support for 550 TB of data written every year make it a strong fit for always-on servers and dense storage arrays. Integrated sensors continuously gauge humidity, pressure, and temperature, allowing the drive to adapt and protect your data even in challenging rack environments. During active use it draws roughly 9.5 W, helping administrators manage power budgets across large deployments.

The Exos X16 line slides easily into hyperscale data centers, on-premises backup servers, and professional NAS enclosures. Video editors who juggle multi-terabyte project files, IT teams building virtualization clusters, or security departments maintaining extended retention times for surveillance footage will all appreciate the mix of space, endurance, and straightforward SATA compatibility.
