ST20000NM005E Seagate Exos X22 20TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for nearline tiers and scale-out storage with the ST20000NM005E

The ST20000NM005E is a 20TB 3.5in internal SATA enterprise HDD designed for capacity-first architectures in rack servers, storage nodes, and nearline arrays where predictable throughput and consistent latency matter more than flash-class IOPS. In modern CPU platforms, the drive is typically deployed behind a SAS/SATA HBA or RAID controller, enabling balanced host offload, queue-depth tuning, and multi-drive aggregation to match core and memory bandwidth in backup, object, and repository workflows.

With CMR recording, a 7200 RPM spindle, and a 512MB cache, ST20000NM005E supports sustained streaming and mixed sequential workloads while maintaining stable write behavior under long retention cycles. The helium-filled design and integrated humidity sensor improve mechanical efficiency for dense chassis layouts, while 4Kn/512e selectable logical formats help align the storage layer to hypervisor, database, or object store requirements. PowerChoice and PowerBalance features allow fleet-level power governance for large drive counts without compromising availability.

Why Choose the ST20000NM005E?

The ST20000NM005E delivers a strong density-to-slot ratio for scale-out capacity tiers, reducing rack footprint and simplifying expansion plans across NAS/SAN nearline pools and bulk repositories. Built for 24x7 datacenter duty with 2.5M hours MTBF, ST20000NM005E supports predictable lifecycle planning, secure decommissioning via Instant Secure Erase, and consistent fleet behavior in multi-bay systems.

Seagate engineering prioritizes reliability under continuous operation, focusing on vibration-aware mechanics, controlled power profiles, and firmware behavior tuned for enterprise storage environments. This approach helps align the ST20000NM005E to standard data centre practices for serviceability, monitoring, and long-term capacity growth.

Key Applications:

• Scale-out object storage
• Backup and archive tiers
• NAS/SAN nearline capacity pools
• Log retention repositories
• Media libraries and cold/warm datasets
