ST16000NM001H Seagate Exos X24 16TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Enterprise Nearline HDD featuring CMR SATA throughput with the ST16000NM001H

The ST16000NM001H is a 16TB 3.5in enterprise nearline HDD designed to scale capacity in modern CPU-centric storage nodes and dense JBOD shelves where predictable streaming performance is required. In architectures that prioritize core count and memory bandwidth for services such as virtualisation, file/object layers, and backup orchestration, the ST16000NM001H provides cost-efficient bulk storage while keeping operational behavior consistent under 24x7 duty cycles.

With a single-port SATA interface, the ST16000NM001H aligns with broadly deployed HBA and RAID controller platforms and integrates cleanly into PCIe-attached storage topologies without forcing changes to the host expansion model. CMR recording supports stable write characteristics for rebuilds and continuous ingest, while a 512MB cache improves command coalescing and sequential transfer efficiency. Support for 4Kn/512e sector formats simplifies migration planning across mixed OS and hypervisor estates.

Why Choose the ST16000NM001H?

The ST16000NM001H delivers a practical density-to-bay ratio for nearline tiers, enabling higher usable capacity per rack unit while maintaining operational resilience expected in enterprise storage pools. By combining predictable performance with security features and long-life reliability targets, the ST16000NM001H supports scalable deployments where consistent fleet behavior, straightforward service workflows, and controlled data lifecycle management are priorities.

Seagate engineers the Exos platform for data centre duty with focus on sustained workloads, vibration-tolerant mechanics, and qualification for multi-drive enclosures. The ST16000NM001H further aligns with security and compliance requirements through Self-Encrypting Drive capabilities and Instant Secure Erase, reducing exposure during decommissioning while keeping deployment models familiar.

Key Applications:

• Large-scale nearline capacity tiers in servers and JBODs
• Backup and archive repositories
• Virtualisation bulk storage datastores
• File and object storage platforms
