ST3000NM0025 Seagate Exos 3TB SAS 128 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SAS HDD for 24x7 Capacity Tiers with the ST3000NM0025

The ST3000NM0025 is a 3TB, 3.5-inch internal Seagate Exos enterprise HDD engineered for predictable throughput and sustained availability in SAS JBOD and RAID shelves, where storage controllers, not onboard compute, define the performance envelope. In modern server platforms, the ST3000NM0025 aligns with SAS backplanes and HBAs to support consistent queue handling and mixed read/write profiles under continuous duty cycles.

Designed for capacity tiers behind compute nodes, the ST3000NM0025 complements CPU- and PCIe-driven architectures by offloading bulk data retention to a 7200RPM CMR media path with 128MB cache, enabling stable streaming and rebuild behavior. Its 512n sector format and T10 DIF support fit end-to-end protection stacks in SAN/NAS back-end designs, while PowerChoice power management helps control thermal and power budgets across dense chassis and multi-bay enclosures.

Why Choose the ST3000NM0025?

The ST3000NM0025 provides an enterprise-centric density-to-reliability profile for scale-out storage where consistent operation matters more than peak IOPS. With a 2.0M-hour MTBF rating, DIF-enabled integrity paths, and a single-port SAS interface optimized for standard dual-controller topologies at the enclosure level, the ST3000NM0025 is a practical building block for predictable expansion, fleet standardization, and controlled lifecycle operations.

Seagate designs Exos-class drives with a focus on datacenter duty cycles, firmware behavior under sustained workloads, and compatibility with common SAS storage stacks. This engineering approach supports long-run stability in environments that prioritize monitoring, serviceability, and alignment with modern rack-scale power and thermal constraints.

Key Applications:

• SAS JBOD expansion shelves
• RAID capacity arrays and rebuild domains
• SAN/NAS back-end capacity tiers
• Backup and archive repositories
• Mixed read/write datacenter workloads
