Seagate Exos X16 ST14000NM005G 14TB 3.5" SATA 7200 RPM 256MB enterprise internal hard drive

Capacity and interface

This 14TB 3.5-inch enterprise hard drive uses a SATA 6.0Gb/s interface and spins at 7200 RPM with a 256MB cache. It is built for nearline storage in servers and arrays where high capacity and consistent response rates are required. The helium-filled design helps lower power consumption per terabyte in dense deployments.

Who this suits and who should look elsewhere

It suits integrators building maximum-density racks that can accommodate the 25.4mm height and need a 550TB per year workload rating with a 2.5M-hour MTBF. It is not for desktop workloads that exceed the annual transfer limit or for bays that cannot accept a 3.5-inch form factor.

Deciding specification

The 550TB per year workload rate limit is the single figure that determines whether this drive matches the intended write intensity. Exceeding that threshold risks reduced reliability and falls outside the design envelope.
