Enterprise storage drive

The Seagate Exos X16 ST16000NM003G is a 16TB 3.5-inch internal hard drive built for enterprise storage. It spins at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. Helium-sealed construction and a 2.5M-hour MTBF rating support continuous operation in data-centre environments.

High-capacity rack deployments

This drive suits operators who need the highest 16TB hard drive performance with enhanced caching for cloud or massive scale-out applications. PowerBalance technology optimises watts per terabyte, while Seagate Secure features simplify drive retirement. Buyers who need more than 16TB per bay, or who require a different interface than SATA, should look at something else.

SATA 6.0Gb/s interface

The single specification that decides fit is the SATA 6.0Gb/s interface. The drive delivers an average latency of 4.16ms and uses 512E/4KN sector formats with SED encryption. Physical dimensions are 147.00mm long, 101.85mm wide and 26.11mm high. Verify that the host system provides a SATA 6.0Gb/s port and 3.5-inch mounting space before purchase.
