ST10000NM020B Seagate Exos 7E10 10TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS HDD designed for scalable arrays with the ST10000NM020B

The ST10000NM020B is a 10TB 3.5-inch enterprise HDD engineered for 24/7 duty in SAS storage domains where predictable latency and consistent throughput are required across multi-drive shelves. In modern dual-controller storage platforms and server backplanes, its SAS interface supports robust pathing and operational continuity while maintaining straightforward integration with existing RAID and HBA ecosystems.

For capacity-centric nodes, the ST10000NM020B uses 7200 RPM CMR recording and a 256MB cache to sustain sequential performance profiles that align with backup windows, tiered storage, and bulk repositories. Flexible sector format support for 512e and 4Kn, with adjustable logical sector sizing, enables clean alignment to file systems, object stores, and virtualization stacks while reducing the risk of write amplification during migrations or mixed-format deployments.

Why Choose the ST10000NM020B?

The ST10000NM020B delivers an enterprise-focused density-to-reliability balance for scale-out nodes and RAID arrays, where drive count, rebuild behavior, and serviceability determine effective capacity. With 2.0M hours MTBF, Protection Information (PI) support, and SED security with Instant Secure Erase, the ST10000NM020B is suited to environments that require auditable data handling, controlled decommissioning, and consistent operational lifecycle management.

Seagate designs the Exos enterprise family with an emphasis on continuous-operation durability, predictable firmware behavior, and qualification for modern data centre storage standards. PowerChoice power management helps operators tune the ST10000NM020B for rack-level efficiency targets without compromising availability expectations in always-on storage tiers.

Key Applications:

• Data centre bulk storage
• RAID arrays and JBOD shelves
• Backup and archive repositories
• Tiered storage capacity layers
• Scale-out storage nodes
