ST16000NM0002 Seagate Exos 2X18 16TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS HDD featuring scale-out capacity efficiency with the ST16000NM0002

The ST16000NM0002 is a 16TB 3.5-inch internal enterprise HDD engineered for 24/7 data centre operation where CPU and GPU resources are constrained more by storage throughput consistency and fleet reliability than by peak compute. In modern x86 and ARM server platforms, it integrates cleanly into SAS HBAs and RAID controllers, aligning with predictable latency requirements for bulk storage nodes and nearline tiers.

Designed for dense storage shelves and scale-out architectures, the ST16000NM0002 supports 512e and 4Kn sector formats to match OS, hypervisor, and object-storage stack expectations while maintaining data integrity across large volumes. Its 7200 RPM CMR design and 256MB cache are optimised for sustained sequential and mixed streaming I/O typical of backup targets and capacity-focused SAN/NAS pools. Helium-filled mechanics and integrated power management support stable thermals and power budgeting within PCIe expansion and storage backplanes, enabling consistent performance per rack unit as arrays scale.

Why Choose the ST16000NM0002?

The ST16000NM0002 delivers a practical density-to-performance profile for enterprise storage tiers that prioritise predictable service levels, straightforward scalability, and controlled operational risk. With a 2.5M-hour MTBF and a platform built for continuous duty cycles, the ST16000NM0002 is well suited to multi-drive deployments where fleet behaviour, not individual-drive peak metrics, determines uptime and maintenance cadence.

Seagate designs the Exos platform with an engineering focus on long-life mechanical stability, tight manufacturing tolerances, and compatibility with common data centre standards for SAS backplanes, enclosure management, and storage qualification workflows.

Key Applications:

• Data centre bulk storage
• Scale-out object storage
• Backup repositories
• Archive tiers
• Nearline NAS/SAN storage pools
