ST16000NM001G Seagate Exos X16 16TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA Nearline HDD featuring helium-sealed CMR capacity with the ST16000NM001G

The ST16000NM001G is a 16TB 3.5in enterprise internal HDD engineered for scale-out capacity tiers in rack servers and JBOD enclosures where predictable latency and sustained throughput matter more than flash-class IOPS. In modern CPU-based storage nodes and storage gateways, it complements PCIe expansion for HBAs, RAID controllers, and high-speed NICs by delivering high capacity per bay over a standard SATA backplane, enabling efficient density in 1U/2U platforms.

For memory-centric file systems and object storage services, the ST16000NM001G supports CMR recording to maintain stable write behavior under rebuild and ingestion pressure. Advanced Format flexibility with 4Kn native and 512e emulation helps align logical sector sizing with OS, hypervisor, and array requirements, reducing translation overhead and simplifying fleet standardisation. With 7200 RPM operation and a 256MB cache, the ST16000NM001G is suited to RAID groups, erasure-coded pools, and backup targets where consistent streaming performance and serviceability are key.

Why Choose the ST16000NM001G?

The ST16000NM001G delivers an enterprise-appropriate density-to-power profile and a deployment model optimised for large fleets: fewer spindles per usable terabyte, efficient bay utilisation, and predictable integration into hot-swap storage planes. Designed for 24x7 duty cycles and large array environments, it supports scalable capacity growth while maintaining operational consistency across mixed server and enclosure footprints.

Seagate designs the Exos enterprise line around controlled thermals, helium-sealed mechanical stability, and qualification for data centre vibration and duty-cycle expectations. This engineering focus aligns with modern operational standards for nearline storage, where reliability metrics and long-life platform compatibility are critical.

Key Applications:

• RAID arrays in rack servers
• JBOD scale-out storage
• Backup and archive tiers
• Object and file storage capacity pools
• 24x7 nearline data repositories
