ST20000NM004E
High-Density 3.5in Enterprise SAS Nearline HDD featuring helium-sealed CMR with the ST20000NM004E
The ST20000NM004E is a 20TB 3.5in internal enterprise HDD designed for scale-out server storage where CPU and memory resources are allocated to data services rather than local compute. In dense storage nodes, the ST20000NM004E supports predictable throughput for sequential and mixed read/write streams, enabling consistent behavior across distributed file and object platforms.
Architecturally, the single-port SAS interface enables deterministic link management in enterprise backplanes, while 512e/4Kn sector options allow alignment with modern RAID/HBA and software-defined storage stacks. With 7200RPM performance and large cache, the ST20000NM004E is optimized for nearline tiers that must sustain steady transfer rates without the latency and cost profile of flash. Helium sealing supports stable thermals and power efficiency in hot-plug 24/7 chassis designs, improving rack-level capacity planning in multi-drive enclosures.
Why Choose the ST20000NM004E?
The ST20000NM004E delivers a pragmatic density-to-throughput balance for enterprise bulk storage, reducing drive count per usable TB and simplifying expansion in SAS-based shelves and servers. For architects standardizing on nearline pools, the ST20000NM004E offers consistent deployment logic: scale capacity linearly, maintain serviceability with hot-swap bays, and align reliability targets with 2.5M-hour MTBF expectations in always-on environments.
Seagate engineers the Exos platform for data centre duty cycles, emphasizing mechanical stability, firmware tuned for sustained workloads, and predictable behavior under vibration and thermal variation. This approach aligns the ST20000NM004E with modern operational standards for high-density racks, controlled power envelopes, and long-life fleet management.
Key Applications:
- Scale-out storage nodes
- Backup and archive tiers
- Nearline file repositories
- Object storage pools
- Data centre bulk storage
At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your ST20000NM004E rollout and from bulk order discount options that support standardized fleet expansions across racks and storage shelves.
