ST16000NM002G Seagate Exos X16 16TB SAS 256MB 3.5" Server HDD

High-Density 3.5in Enterprise SAS HDD for 24/7 Capacity Tiers with the ST16000NM002G

The ST16000NM002G is a 16TB 3.5in enterprise HDD designed to anchor dual-controller SAS storage arrays, JBOD shelves, and SAN/NAS capacity tiers where predictable throughput and continuous duty cycles are mandatory. In CPU- and memory-centric platforms running virtualisation clusters, backup software, and scale-out file services, the ST16000NM002G provides consistent block storage behaviour and high capacity per bay without shifting the system architecture toward SSD-only cost profiles.

Integrated into modern servers with PCIe-based SAS HBAs or RAID controllers, the ST16000NM002G fits cleanly into 12Gb/s SAS domains and multipath designs via its dual-port interface for resilient fabric attachment. CMR recording supports stable write performance under rebuild and sequential ingest, while Advanced Format 512e/4Kn selectable logical sectors simplify alignment across mixed operating systems and storage stacks. A 256MB cache and 7200RPM spindle target balanced I/O for capacity layers, and hot-plug support streamlines service operations in dense enclosures.

Why Choose the ST16000NM002G?

The ST16000NM002G delivers a strong density-to-slot ratio for capacity tiers while maintaining enterprise reliability characteristics for always-on deployments. Dual-port SAS enables controller failover and path redundancy, supporting scalable expansion in shared SAS or modular array architectures. With 2.5M hours MTBF and T10 DIF/PI data integrity support, the ST16000NM002G aligns with operational requirements for large fleets and automated maintenance workflows.

Seagate engineers the Exos platform for sustained 24/7 service, focusing on controlled vibration behaviour, helium-sealed mechanics, and environmental monitoring with an integrated humidity sensor. This approach supports consistent operation in modern data centre thermals and standardized hot-swap service models.

Key Applications:

• SAS storage arrays and JBOD expansion shelves
• SAN/NAS capacity tiers
• Virtualisation datastores
• Backup and archive repositories
• 24/7 server storage pools
