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

Overview

The Seagate ST12000NM001G is a 12 TB internal hard drive designed to deliver high capacity, speed, and reliability for demanding storage needs. It features a 3.5-inch form factor and connects via a SATA III 6 Gb/s interface, spinning at 7200 rpm to provide sustained transfer rates up to 245 MB per second. This combination makes it well suited for handling large file archives, backups, and continuous data streams in professional environments.

Engineered for durability, the drive offers a 2.5 million-hour mean time between failures and supports an annual workload of 550 TB written, making it ideal for always-on servers and dense storage arrays. Integrated sensors monitor humidity, pressure, and temperature to maintain data integrity even in challenging rack conditions, while its power consumption of approximately 9.5 W helps manage energy use in large deployments.
