ST20000NE000

High-Density 3.5" SATA CMR Enterprise HDD for NAS and Server Capacity Tiers with the ST20000NE000

The ST20000NE000 is a 20TB Seagate IronWolf Pro 3.5" internal SATA HDD engineered for capacity-focused NAS and server platforms where CPU and GPU resources are secondary to predictable storage throughput and consistent latency under multi-user access. In RAID shelves and SMB/enterprise NAS nodes, the ST20000NE000 supports sustained operation profiles that align with modern multi-core host systems and large memory footprints by keeping bulk data close to compute while controlling cost per TB.

Using CMR recording and a 7200 RPM design, the ST20000NE000 is suited to storage architectures built on SATA HBA or RAID controllers attached via PCIe expansion, enabling dense scale-out arrays without the thermal and power complexity of all-flash. Support for 4Kn/512e sector formats helps integrate the ST20000NE000 into mixed OS and hypervisor estates, while cache and firmware behaviors are optimized for RAID integrity and steady rebuild characteristics in always-on environments.

Why Choose the ST20000NE000?

The ST20000NE000 delivers a practical density-to-serviceability ratio for 3.5" bays, allowing IT teams to expand capacity within existing chassis, backplanes, and power budgets. With 24x7 design intent and a 1.2M hour MTBF target, the ST20000NE000 fits scale-out NAS and capacity tiers that must remain predictable during peak concurrency, rebuild cycles, and scheduled protection tasks.

Seagate designs IronWolf Pro drives around controlled vibration tolerance, helium-sealed efficiency, and firmware features intended for multi-drive enclosures. This engineering approach aligns with data centre standards for continuous duty cycles, lifecycle planning, and consistent fleet behavior across RAID groups and storage pools.

Key Applications:

SMB and enterprise NAS RAID arrays
Server bulk capacity tiers
Backup and archive repositories
Media asset libraries and workgroup storage
Local backup targets for workstations

At Happyware - Server Hardware you benefit from non-binding offers tailored to your NAS or server storage rollout with the ST20000NE000, and you can extend the warranty up to 6 years to align drive coverage with enterprise refresh cycles.
