ST4000NM0035 Seagate Exos 4TB SATA 128 MB 3.5" Workstation HDD

High-Density 3.5" Enterprise SATA HDD for 24x7 Capacity Tiers with the ST4000NM0035

The ST4000NM0035 is a 4TB 3.5" internal enterprise HDD engineered for server and storage platforms that prioritise predictable throughput, high duty-cycle operation, and efficient capacity scaling. In modern CPU-centric infrastructures where compute nodes depend on reliable local or shared disk tiers, the ST4000NM0035 supports steady sequential performance for bulk data while maintaining consistent latency characteristics expected in enterprise arrays and storage servers.

Built on CMR recording and a 512n Advanced Format sector model, the ST4000NM0035 is aligned with environments that require broad OS and controller compatibility, straightforward RAID integration, and deterministic rebuild behaviour. Its 7.2K spindle design and 128MB cache complement SATA-based backplanes and PCIe expansion strategies by keeping the storage tier cost-optimised while leaving higher PCIe generations available for NVMe acceleration where needed. PowerChoice power management helps architects balance rack-level power envelopes for dense JBODs, backup repositories, and edge servers.

Why Choose the ST4000NM0035?

The ST4000NM0035 delivers a pragmatic density-to-performance ratio for capacity tiers that must run continuously, making it suitable for standardised fleet deployment across storage nodes. With enterprise-grade mechanics and a 2.0M-hour MTBF target, the ST4000NM0035 supports scalable designs where predictable service life, consistent drive behaviour, and operational continuity are key to reducing maintenance overhead.

Seagate designs the Exos series with a focus on durability, controllable power characteristics, and datacentre-friendly interoperability, enabling dependable integration into SATA server architectures. The ST4000NM0035 reflects this engineering approach through 24x7 duty-cycle capability, ramp load mechanics for handling robustness, and an operating temperature range suited to controlled server airflow.

Key Applications:

• Capacity expansion in servers and JBOD shelves
• Backup and archive repositories
• Bulk data and media libraries
• Edge servers with local datasets
