Seagate Exos X16 12TB 3.5" 7200RPM SAS 12 Gb/s Internal HDD

The Seagate ST12000NM002G is a 12 TB Exos X16 hard drive created for servers and storage arrays that need reliable, around-the-clock performance. It fits any standard 3.5 inch bay and connects through a 12 Gb/s SAS interface, moving data at up to 245 MB/s with help from a 256 MB cache.

This combination of capacity and speed serves virtualisation hosts, content delivery nodes, and analytic clusters that handle large datasets yet have limited rack space. Administrators can stream, back up, and analyse data without being slowed by I/O bottlenecks.

Seagate fills the drive with helium instead of air, a design that reduces internal turbulence, lowers power draw, and keeps temperatures under control when many drives sit side by side. Built-in sensors continuously watch temperature, humidity, and pressure so management software can react before conditions threaten uptime.

Reliability matches the performance story. The drive carries a 2.5 million hour MTBF, an error rate of one in 10¹⁵ bits read, and support for T10 DIF to maintain data integrity. PowerBalance technology balances IOPS and energy use, and hot-plug compatibility lets staff replace or add drives without shutting down a server.

Whether expanding a backup vault, building a private cloud, or refreshing a high-density storage shelf, the Exos X16 provides the space, speed, and durability needed for demanding enterprise workloads.
