ST4000NM0054 Seagate Enterprise Capacity 4TB SAS 128 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS HDD featuring CMR capacity storage with the ST4000NM0054

The ST4000NM0054 is a 4TB, 3.5-inch internal enterprise HDD engineered for 12Gb/s SAS backplanes in Tier-2 capacity arrays and always-on server storage. In RAID groups behind modern SAS HBAs and storage controllers, the ST4000NM0054 prioritises predictable latency and sustained throughput by using CMR recording and a 7200 RPM spindle, making it well-suited for steady mixed read/write patterns typical of file and application services.

Designed for dense rack platforms with PCIe-based RAID/HBA expansion, the ST4000NM0054 integrates cleanly into scalable SAS topologies where multiple drive shelves and dual-port paths are used for high availability. Its 4K native sector format with 512e emulation helps maintain compatibility across operating systems and legacy stacks, while the onboard 128MB cache supports command queuing efficiency under parallel workloads and rebuild scenarios.

Why Choose the ST4000NM0054?

The ST4000NM0054 delivers an enterprise-appropriate density-to-performance balance for capacity tiers where cost-per-TB and reliability matter more than ultra-low latency. With 24/7 duty rating, 2.0M hours MTBF, and a 12Gb/s SAS interface, the ST4000NM0054 supports scalable deployment in RAID volumes and shared storage pools, aligning with predictable expansion planning and operational continuity requirements.

Seagate designs the Enterprise Capacity Series around controlled thermals, consistent firmware behaviour, and long service life in multi-drive enclosures. This engineering focus supports data centre standards for continuous operation, secure handling, and integration into managed storage environments.

Key Applications:

• Tier-2 enterprise SAS arrays
• 24/7 RAID storage for file and application servers
• Backup and archive capacity pools
• Bulk storage for virtualisation repositories
• Nearline data retention and compliance
