ST14000NM002G Seagate Exos X16 14TB SAS 256MB 3.5" Server HDD

High-Capacity 3.5in Enterprise SAS HDD for 24x7 Storage Tiers with the ST14000NM002G

The ST14000NM002G is a 14TB 3.5in enterprise HDD engineered for sustained throughput and predictable latency in data centre servers and storage arrays where capacity density and reliability drive architecture decisions. Built for scale-out platforms rather than CPU- or GPU-bound compute nodes, it complements modern x86 server generations by providing a high-capacity tier behind SAS HBAs and RAID controllers while preserving PCIe lanes for NVMe, high-speed networking, or accelerator expansion.

With dual-port SAS connectivity, the ST14000NM002G supports multipath designs in shared storage and high-availability enclosures, enabling controller failover and resilient backplanes. CMR recording and a 7200 RPM spindle are aligned to consistent write behavior in RAID groups, while Advanced Format support (4Kn native and 512e emulation) simplifies sector-size alignment across mixed OS, hypervisor, and appliance stacks. The 256MB cache is tuned for transactional bursts, and hot-plug capability fits operational models that prioritize serviceability and minimal maintenance windows.

Why Choose the ST14000NM002G?

The ST14000NM002G delivers a strong capacity-per-bay profile for dense 3.5in shelves, supporting scalable pools for backup, archive, and capacity tiers without redesigning chassis layouts. Dual-port SAS and enterprise duty-cycle design enable predictable availability in 24x7 environments, while 2.5M hours MTBF targets long-life fleet deployments where replacement workflows and spares strategy are tightly controlled.

Seagate designs the Exos platform around datacentre operating conditions, balancing thermal characteristics, power efficiency, and vibration tolerance to maintain stable performance in multi-drive enclosures. The engineering focus on enterprise interoperability and lifecycle consistency aligns with standard SAS ecosystems, RAID policies, and modern storage management practices.

Key Applications:

• Capacity tiers for virtualization and file services
• Backup repositories and deduplication targets
• Archive and compliance retention storage
• Scale-out object and content storage
• RAID-based storage arrays and JBOD shelves
