ST8000NM017B Seagate Exos 7E10 8TB SATA 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise Capacity HDD featuring CMR recording with the ST8000NM017B

The ST8000NM017B is an 8TB, 3.5in internal enterprise HDD engineered for SATA-based storage tiers in modern rack servers and workstations where capacity density and predictable latency matter. In CPU-centric platforms that prioritise core count and memory bandwidth for virtualisation or data services, the ST8000NM017B complements DRAM-backed caching and software-defined storage by providing consistent block behaviour for RAID groups and large volume pools.

Designed for broad compatibility across SATA host controllers and backplanes, the ST8000NM017B fits cleanly into PCIe-attached HBA/RAID expansion strategies without forcing a shift to higher-cost all-flash architectures. CMR recording supports stable write performance under sustained ingestion, while 512e and 4Kn formatting options simplify alignment with OS and hypervisor storage stacks. A 7,200 RPM spindle with 256MB cache helps maintain responsive queue handling for mixed sequential and random workloads, and SED hardware encryption enables at-rest protection without consuming CPU cycles.

Why Choose the ST8000NM017B?

The ST8000NM017B delivers a practical density-to-performance profile for capacity-optimised bays, enabling scalable RAID arrays and backup tiers with enterprise duty-cycle expectations. With 24x7 design intent and a 2.0M-hour MTBF target, the ST8000NM017B supports predictable operations in shared storage pools where rebuild behaviour, sustained writes, and long service life influence platform risk.

Seagate designs Exos-class drives around controlled thermals, vibration-aware mechanics, and firmware tuned for datacentre workloads. This engineering focus aligns the ST8000NM017B with standardised server chassis, hot-swap backplanes, and common storage management practices used in enterprise environments.

Key Applications:

• RAID arrays for server and workstation bulk storage
• Backup and archival tiers
• Capacity-optimised software-defined storage
• Log, telemetry, and repository storage
