ST8000NM004A Seagate Exos 7E8 8TB SATA 256 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise HDD featuring 24x7 CMR capacity tiering with the ST8000NM004A

The ST8000NM004A is a 3.5-inch 8TB enterprise SATA HDD designed to anchor high-density storage tiers in CPU-based server platforms where predictable sequential throughput and consistent latency matter more than low-queue NVMe IOPS. In virtualisation hosts and general-purpose rack servers, it complements modern multi-core CPUs by providing economical bulk capacity for warm data, logs, and backup targets without consuming scarce PCIe lanes needed for NICs, accelerators, or NVMe cache devices.

With 7200RPM CMR recording, 256MB cache, and 512e sector formatting, the ST8000NM004A integrates cleanly into standard RAID/HBA stacks and mixed-drive pools. SATA connectivity streamlines expansion across multi-bay chassis, while workload alignment remains clear: capacity-first repositories, retention-focused architectures, and tiered storage designs that use SSDs for hot data and HDDs for sustained bulk writes and long-lived datasets. The ST8000NM004A adds Self-Encrypting Drive security with Instant Secure Erase to support encrypted-at-rest operational models and controlled decommissioning workflows.

Why Choose the ST8000NM004A?

The ST8000NM004A delivers an enterprise-appropriate balance of density, reliability, and operational security for scale-out HDD pools, enabling predictable capacity growth per 3.5-inch bay while keeping platform expansion slots available for PCIe networking and acceleration. Rated for 24x7 duty and engineered for large arrays, it supports consistent deployment across server fleets and storage shelves with a clear lifecycle profile.

Seagate designs the Exos line with a reliability-first engineering approach, aligning firmware, vibration tolerance, and validation practices to modern data centre standards where sustained utilisation, controlled thermals, and serviceability are non-negotiable. The ST8000NM004A is built for enterprise operational continuity, including secure data handling requirements.

Key Applications:

• Capacity tiering in enterprise storage
• Backup and archive repositories
• Virtualisation bulk datastores
• Log and warm-data volumes
• Always-on NAS and HDD pools
