ST8000NM0055

High-Density 3.5-inch Enterprise SATA HDD for 24x7 capacity tiers with the ST8000NM0055

The ST8000NM0055 is a 3.5-inch enterprise HDD engineered for capacity-focused storage tiers in modern server platforms, complementing CPU-dense hosts where memory bandwidth and PCIe lanes are reserved for compute and NVMe cache. As a SATA device, the ST8000NM0055 fits cleanly into established backplanes and RAID controllers, enabling predictable integration alongside mixed SSD/HDD architectures for balanced performance and cost per TB.

Designed around 7200RPM CMR recording, the ST8000NM0055 provides consistent write behavior suited to rebuild-sensitive arrays and sustained ingest patterns. The 4Kn format with 512e emulation supports contemporary operating systems and storage stacks, while PI (Protection Information) strengthens end-to-end data integrity in enterprise controllers. For secure deployments, the ST8000NM0055 adds SED capabilities to align with at-rest encryption requirements without shifting encryption overhead to the CPU.

Why Choose the ST8000NM0055?

The ST8000NM0055 targets high-density RAID arrays and JBOD enclosures where predictable latency, serviceability, and 24x7 duty cycles matter more than peak IOPS. With enterprise power management via PowerChoice and a 2.0M-hour MTBF profile, the ST8000NM0055 supports scalable capacity expansion in standardized storage nodes and consolidated backup repositories while maintaining operational stability across large drive counts.

Seagate designs Exos-class drives with an engineering focus on datacenter workload consistency, controlled vibration behavior, and firmware tuned for multi-drive environments. This reliability-first approach aligns with modern data centre standards for thermal envelopes, continuous operation, and secure lifecycle management in shared storage infrastructures.

Key Applications:

Capacity tier in RAID arrays
JBOD expansion shelves
Backup and archive repositories
General-purpose file and content storage
Bulk storage pools for virtualized environments

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your needs and the option to extend the warranty up to 6 years, supporting predictable procurement and long-term lifecycle planning for ST8000NM0055 deployments.
