ST28000NM003K Seagate Exos M 28TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Nearline Enterprise HDD architecture with predictable CMR performance in the ST28000NM003K

The ST28000NM003K is engineered as a high-capacity 3.5in internal SATA HDD for dense nearline tiers where predictable write behavior and consistent latency matter more than peak IOPS. In modern x86 server platforms, it complements CPU-driven storage services such as backup, object indexing, and capacity pooling by prioritizing sustained throughput and deterministic rebuild characteristics over NAND-style acceleration.

Designed for SATA 6Gb/s backplanes and host bus adapters across PCIe expansion domains, the ST28000NM003K integrates cleanly into JBOD shelves and RAID controllers without special firmware dependencies. Its 4Kn/512e formatting supports contemporary file systems and scale-out stacks, while a large cache and 7200 RPM profile improve sequential efficiency for ingest and restore pipelines. The CMR recording method makes the ST28000NM003K a stable choice for parity RAID, avoiding the write-amplification risks of SMR in mixed arrays.

Why Choose the ST28000NM003K?

The ST28000NM003K delivers an enterprise-appropriate density-to-bay ratio for capacity-first architectures, reducing rack unit consumption in nearline pools and archive grids. With 24x7 duty design, high MTBF targets, and features supporting power governance and secure decommissioning, the ST28000NM003K scales predictably from a few drives per server to multi-shelf RAID sets with consistent operational behavior.

Seagate designs the Exos family around data center serviceability, focusing on reliability telemetry, environmental resilience, and compliance with standard SATA infrastructure. The platform approach emphasizes controlled power characteristics, helium-assisted mechanical efficiency, and lifecycle features such as Instant Secure Erase to align with enterprise retention and disposal workflows.

Key Applications:

• Backup and restore repositories
• Archive and compliance storage
• Object and scale-out storage nodes
• General-purpose capacity pools
• RAID arrays and SATA JBOD shelves
