Seagate Exos X14 12TB 3.5" 7200RPM SATA III Internal HDD

The Seagate ST12000NM0008 is a 12 TB 3.5 inch internal hard drive that connects through a SATA III 6 Gb /s interface and spins at 7200 rpm. It delivers enterprise-class capacity in a familiar desktop form factor, making it a straightforward upgrade for servers and storage enclosures that need more space without changing their infrastructure.

With a 256 MB cache and a sustained transfer rate that reaches up to 261 MB/s, the drive moves large files quickly and keeps multi-user workloads responsive. Average latency sits at 4.16 ms, so databases, virtual machines, and backup jobs can access data with minimal delay.

Reliability is at the core of this model. A helium-sealed enclosure lowers internal turbulence, which reduces wear and helps the drive achieve a 2.5 million-hour MTBF and an annualized failure rate of 0.35 percent. Built-in pressure sensors continually monitor the environment, ensuring consistent performance in high-density racks that run around the clock.

For teams managing power budgets, the PowerBalance feature lets administrators tune the drive’s performance profile to strike an optimal balance between input/output operations per second and energy consumption. This capability is valuable in scale-out data centers where even small efficiency gains add up over thousands of drives.

Whether you are expanding a cloud storage pool, building a high-capacity RAID array for video archives, or setting up a reliable off-site backup target, the Exos X14 platform provides the space, speed, and durability that modern data workloads demand.
