ST1000NM0023 Seagate Constellation ES.3 1TB SAS 128 MB 3.5" HDD

High-Performance 3.5-inch Enterprise SAS HDD featuring SED security and integrity protection with the ST1000NM0023

The ST1000NM0023 is a 3.5-inch internal SAS hard drive designed for capacity tiers in rack servers, JBOD shelves, and RAID arrays where predictable latency, controlled power draw, and continuous duty cycles are required. In modern CPU platforms with high core counts, it aligns with storage architectures that separate performance SSD tiers from resilient HDD pools, keeping backup-to-disk and general-purpose datasets cost-efficient while maintaining enterprise controls.

Within PCIe-based server designs, the ST1000NM0023 complements SAS HBAs and RAID controllers by providing stable 7,200 RPM CMR behavior for consistent rebuild characteristics and streaming workloads. Its cache and error-recovery behavior support queue depth typical of multi-tenant storage, while Protection Information and end-to-end data integrity help reduce silent corruption risk across controller, expander, and media paths. For security-focused deployments, the ST1000NM0023 enables self-encrypting drive workflows that integrate with key management policies without changing the storage topology.

Why Choose the ST1000NM0023?

The ST1000NM0023 delivers an enterprise-appropriate density-to-performance balance for 3.5-inch SAS bays, allowing scalable population of capacity shelves with consistent operational characteristics. By combining SED capability, integrity-protected data paths, and 24x7 reliability targets, the ST1000NM0023 supports standardized deployment across mixed server fleets and storage pools while simplifying compliance-driven handling of decommissioned media.

Seagate designs the Constellation ES.3 family with a focus on predictable behavior under sustained load, robust error correction, and firmware tuned for array environments, aligning with data centre expectations for serviceability, controlled power management, and long-life operation.

Key Applications:

• SAS JBOD capacity shelves
• RAID arrays in rack servers
• Backup-to-disk repositories
