ST10000NM0478 Seagate Exos X14 10TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise Nearline HDD featuring helium-sealed CMR storage with the ST10000NM0478

The ST10000NM0478 is a 10TB 3.5in internal enterprise HDD designed for nearline tiers in modern x86 server and storage platforms where CPU generation and memory architecture are optimized for throughput, caching, and data services rather than compute acceleration. In NAS, SAN, and scale-out storage nodes, the ST10000NM0478 aligns with DDR4/DDR5 memory-backed write buffering and RAID parity operations, sustaining predictable sequential performance under 24x7 duty-cycle conditions.

As a SATA single-port drive, the ST10000NM0478 integrates cleanly into PCIe-based storage controllers and HBAs where PCIe bandwidth is allocated to networking and accelerator expansion, while bulk capacity is delivered through dense 3.5in bays. CMR recording supports consistent rebuild behavior in RAID arrays, and selectable 512e/4Kn logical sector formats simplify alignment with filesystem block sizes, object storage layouts, and backup software requirements. A 7200RPM spindle and onboard cache help reduce latency for mixed read workloads in nearline repositories.

Why Choose the ST10000NM0478?

The ST10000NM0478 provides a balanced density-to-performance profile for capacity-driven tiers, enabling predictable scaling by adding shelves or nodes without re-architecting the storage stack. It is engineered for enterprise reliability with a helium-filled design, an integrated humidity sensor, and a 2.5M-hour MTBF target, supporting controlled expansion in RAID, NAS, or archival pools while maintaining operational consistency.

Seagate designs Exos-class drives with a focus on long-life mechanics, firmware tuned for sustained duty cycles, and power management features such as PowerChoice and PowerBalance to support data centre standards for efficiency and serviceability across large drive populations.

Key Applications:

• RAID arrays and storage shelves
• NAS and SAN nearline tiers
• Backup repositories
• Archival and bulk datasets
• Scale-out object storage capacity nodes
