ST16000NT001_2 Seagate IronWolf Pro 16TB SATA 256 MB 3.5" Server HDD

High-Capacity 3.5-inch SATA NAS Enterprise HDD with CMR reliability using the ST16000NT001_2

The ST16000NT001_2 is a 16TB internal enterprise HDD designed for SMB and enterprise NAS arrays where capacity, predictable latency, and RAID consistency are required. As a 3.5-inch SATA drive, it integrates cleanly into standard hot-swap bays and storage shelves, providing a cost-efficient nearline tier for file services, backup targets, and bulk repositories without shifting the platform to PCIe or NVMe architectures.

Built on CMR recording with a 7200 RPM spindle and 256MB cache, ST16000NT001_2 is engineered to sustain mixed sequential and random I/O patterns typical of multi-user NAS and virtualised datastore environments. The 512e/4Kn emulation supports modern alignment requirements across hypervisors and NAS operating systems, while the helium-filled design improves platter efficiency and thermals for dense enclosures operating 24x7. This positions ST16000NT001_2 as a dependable SATA capacity layer behind compute nodes, GPUs, and high-performance NVMe tiers, where the goal is to retain scale-out storage economics while maintaining deterministic rebuild behaviour in RAID sets.

Why Choose the ST16000NT001_2?

The ST16000NT001_2 delivers a strong density-to-bay ratio for NAS shelves and 2U/4U storage servers, enabling growth in usable capacity without increasing rack footprint. With a 2.5M-hour MTBF profile and workload alignment for continuous duty cycles, ST16000NT001_2 supports scalable deployment across multi-drive arrays while keeping SATA interoperability and serviceability straightforward for enterprise operations.

Seagate designs its enterprise NAS HDDs with a focus on sustained reliability, vibration-tolerant operation in populated enclosures, and compatibility with current data centre and edge storage standards. The included data protection approach, including a 3-year data recovery service, complements operational resilience strategies.

Key Applications:

• SMB and enterprise NAS RAID arrays
• Backup and archive repositories
• Nearline capacity tiers for mixed workloads
