ST14000NM003G Seagate Exos X16 14TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for Scale-Out Capacity with the ST14000NM003G

The ST14000NM003G is a 14TB 3.5in enterprise HDD designed for capacity-first server and storage nodes where CPU and memory resources are optimized for throughput rather than compute acceleration. In typical x86 platforms, it complements modern multi-core processors and high-memory configurations by sustaining large sequential streams and predictable block access patterns without consuming PCIe lanes needed for NICs, HBAs, or NVMe tiers.

Built on 7200RPM CMR recording with 256MB cache, the ST14000NM003G supports architectures that rely on SATA backplanes in dense JBOD or RAID shelves, enabling straightforward expansion across controllers and enclosures. Dual sector-format compatibility (512e and 4Kn) simplifies alignment with OS and hypervisor standards, while helium sealing, a humidity sensor, and power-management features help stabilize thermals and power envelopes in always-on racks.

Why Choose the ST14000NM003G?

The ST14000NM003G delivers a practical density-to-power profile for large capacity pools where consistent behavior and serviceability matter more than peak IOPS. With enterprise-class endurance for 24x7 duty cycles and a 2.5M-hour MTBF, it scales cleanly in multi-shelf deployments, supporting predictable fleet operations, uniform sparing strategies, and controlled rebuild domains in RAID and erasure-coded designs.

Seagate engineers the Exos family for data centre reliability, focusing on vibration-tolerant mechanics, tight manufacturing controls, and qualification for sustained workload operation. The platform aligns with modern storage standards by supporting mixed sector-format requirements and power governance features that help maintain rack-level efficiency targets.

Key Applications:

• Scale-out object storage
• SATA JBOD capacity expansion
• RAID storage arrays
• Backup and archive repositories
• NAS and private cloud storage pools
