ST10000NM016G Seagate Exos X18 10TB SAS 256 MB 3.5" Server HDD

High-Density 3.5-inch Nearline SAS Enterprise HDD featuring secure-at-rest storage with the ST10000NM016G

The ST10000NM016G is a 10TB 3.5-inch enterprise nearline HDD built for 24/7 tiers in SAN, NAS, and scale-out storage where predictable throughput and controlled operational risk matter. In modern server platforms, the ST10000NM016G integrates cleanly behind SAS3 12Gb/s HBAs and expanders, aligning with dual-controller backplanes and high-bay density enclosures without consuming PCIe lanes that must remain available for GPU/CPU accelerators and NIC expansion.

Architecturally, the ST10000NM016G supports CMR recording at 7200 RPM with a 256MB cache to sustain steady sequential performance while maintaining stable behavior under mixed queue depths typical of object storage and backup ingest. For infrastructure standardization, logical sector sizing can be configured for 512e or 4Kn to match OS, RAID, and file-system alignment policies. PowerChoice/PowerBalance features help operators tune idle and active profiles across large fleets, improving rack-level efficiency while preserving service-level consistency.

Why Choose the ST10000NM016G?

The ST10000NM016G delivers a practical density-to-performance ratio for nearline SAS tiers, with enterprise reliability characteristics suited to large arrays and continuous duty cycles. With self-encrypting drive capability, FIPS 140-3 support, Instant Secure Erase, and Protection Information, the ST10000NM016G fits deployments where data-at-rest controls, chain-of-custody, and predictable lifecycle operations are mandatory across scalable storage domains.

Seagate designs the Exos platform with an engineering focus on sustained data-center operation, leveraging a helium-filled architecture, humidity sensing, and robust firmware controls to support consistent behavior in multi-drive enclosures and modern availability standards.

Key Applications:

• Nearline SAN/NAS storage tiers
• Scale-out object storage
• Backup and archive repositories
• Compliance-focused encrypted storage
• High-density JBOD enclosures
