ST14000NM004G Seagate Exos X16 14TB SAS 256 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SAS Nearline HDD featuring CMR durability with the ST14000NM004G

The ST14000NM004G is a 14TB Seagate Exos X16 enterprise hard drive engineered for 24x7 data centre capacity tiers where predictable latency, sustained throughput, and long service life matter more than peak IOPS. Integrated into modern storage nodes with multi-core CPU platforms and high-memory controllers, it supports large ARC/DRAM caching strategies while the drive’s own cache helps smooth sequential write bursts typical of ingest and backup windows.

With SAS 12Gb/s connectivity, the ST14000NM004G aligns to dual-ported, high-availability backplanes and PCIe-attached HBAs in dense storage servers, enabling scalable expansion without oversubscribing shared fabrics. CMR recording supports consistent performance under heavy write workloads, while Advanced Format 512e/4Kn flexibility simplifies integration across mixed-sector arrays and software-defined storage stacks focused on object, file, and cold/warm block tiers.

Why Choose the ST14000NM004G?

The ST14000NM004G delivers a strong density-to-bay ratio for nearline capacity pools, reducing rack footprint and power per TB in SAS-based storage arrays. For enterprise reliability, the platform adds T10 DIF end-to-end data integrity and SED hardware encryption to support secure, scalable deployments where data protection, predictable rebuild behavior, and lifecycle management are core operational requirements.

Seagate designs the Exos family with an engineering focus on consistent fleet behavior, qualification in enterprise enclosures, and long-term serviceability aligned to modern data centre standards. The ST14000NM004G is built to integrate cleanly into monitored environments, supporting integrity and security features expected in regulated storage architectures.

Key Applications:

• Scale-out object storage
• File storage and NAS capacity tiers
• Backup and recovery repositories
• Cold and warm data archives
• Capacity expansion for SAS storage arrays
