Seagate ST16000NM004J Exos X18 16TB Enterprise Hard Drive

Flagship Enterprise Storage for Hyperscale Cloud Environments

The Seagate ST16000NM004J Exos X18 16TB Enterprise Hard Drive is a high-capacity SAS drive designed for hyperscale cloud data centers, massive scale-out infrastructure, and demanding enterprise storage applications. As the flagship of the Seagate X class, the Exos X18 delivers the highest storage density available, offering more petabytes per rack for organizations that need to maximize capacity while minimizing physical footprint.

Built for Rack-Space Efficiency at Scale

This drive is made for data centers and enterprises that need to fit as much storage as possible into limited rack space. A helium sealed-drive design lowers total cost of ownership through reduced power consumption and weight compared to air-filled drives, while proven helium side-sealing weld technology adds handling robustness and leak protection during shipping and installation. Digital environmental sensors continuously monitor internal drive conditions to help maintain optimal performance over the drive's operational lifespan.

Reliable, High-Performance Enterprise Design

The Exos X18 is designed to support data analytics capabilities and dense storage architectures, delivering data transfer rates of up to 270MB/s alongside a 256MB cache buffer for strong sustained performance. It carries a workload rating of 550TB per year and a 2.5-million-hour MTBF rating, reflecting the reliability standard expected of Seagate's enterprise-class drives. Customizable PowerChoice and PowerBalance power options allow data centers to optimize energy consumption during both active use and idle periods, helping tailor performance to specific operational needs.

Built-In Data Security

The drive offers password protection and AES-256 hardware encryption through Seagate Secure technology, helping keep sensitive enterprise data protected. This same technology also supports safe, fast, and easy drive retirement at end of life, simplifying secure decommissioning for IT departments managing large storage fleets.
