ST16000NM005H Seagate Exos X24 16TB SAS 512 MB 3.5" Server HDD

High-Density 3.5in SAS Nearline Enterprise HDD featuring dual-port encryption-at-rest with the ST16000NM005H

The ST16000NM005H is a 16TB Seagate Exos X24 nearline HDD engineered for capacity-first tiers in modern server and storage platforms where compute nodes (x86 CPU generations) feed large SAS backplanes and JBOD shelves at scale. In mixed virtualization, backup, and object environments, the drive aligns with architectures that prioritize predictable throughput, queue depth handling, and consistent latency profiles over peak IOPS, enabling efficient CPU and memory allocation for deduplication, erasure coding, and data services.

Designed for 12Gb/s SAS fabrics, the ST16000NM005H integrates cleanly into PCIe-attached SAS HBAs and expander-based topologies, supporting hot-plug service workflows and high-availability designs. CMR recording, 512MB cache, and support for 512e and 4Kn sector formats simplify fleet standardization across operating systems and storage stacks, while dual-port connectivity strengthens path redundancy in clustered controllers and scale-out nodes.

Why Choose the ST16000NM005H?

The ST16000NM005H delivers a strong density-to-slot ratio for 24x7 nearline pools, reducing rack footprint and power-per-terabyte while maintaining enterprise reliability expectations. Its dual-port SAS design supports multipath configurations for scalable deployments, and built-in security and integrity functions help keep data services resilient as capacity and node counts grow.

Seagate’s Exos engineering focuses on sustained operation in high-vibration, high-bay environments, emphasizing firmware consistency, stringent validation, and compatibility with data centre standards for serviceability and lifecycle management. The ST16000NM005H reflects this approach with features aimed at secure operations and long-term fleet stability.

Key Applications:

• Bulk capacity storage arrays
• Scale-out and object storage
• Backup and archive tiers
• Nearline data lakes
• Encrypted data-at-rest repositories
