ST14000NM005G Seagate Exos X16 14TB SATA 256 MB 3.5" Server HDD

High-Capacity 3.5" Enterprise SATA HDD for 24x7 Data Centre Storage with the ST14000NM005G

The ST14000NM005G is a 14TB Seagate Exos X16 3.5" internal HDD engineered as the capacity tier for modern server and storage platforms, complementing CPU-dense nodes and GPU-focused compute by offloading bulk datasets to reliable rotational media. In architectures where DDR5 memory and NVMe tiers are reserved for latency-critical paths, the ST14000NM005G provides predictable throughput and sustained sequential performance for backup targets, JBOD shelves, and nearline repositories.

Designed for SATA backplanes and RAID controllers, the ST14000NM005G supports 4Kn via 512e emulation with adjustable logical sector sizing to align with host OS and filesystem standards. CMR recording enables consistent write behavior in parity RAID sets and scale-out SDS clusters, while PowerChoice and PowerBalance features help manage rack-level power envelopes. Integrated Instant Secure Erase (ISE) simplifies secure decommissioning workflows in shared data centre environments.

Why Choose the ST14000NM005G?

The ST14000NM005G delivers an efficient density-to-slot profile for expanding capacity without increasing chassis count, making it well suited to scale-out storage nodes and high-bay JBOD deployments. With enterprise reliability targets including 2.5M hours MTBF and 24x7 duty design, the ST14000NM005G supports predictable operations in multi-drive arrays where fleet consistency and service continuity are critical.

Seagate designs the Exos family with a data centre engineering focus, using helium-filled mechanics, a humidity sensor, and controlled power management to maintain stable operation across diverse thermal and airflow conditions. This approach aligns with enterprise serviceability expectations and long-lived platforms that standardise on SATA for large-capacity tiers.

Key Applications:

• Bulk storage for rack servers and JBOD enclosures
• Backup repositories and archival tiers
• Scale-out SDS and object storage clusters
• High-capacity SATA RAID arrays (CMR)
