ST4000NM0075 Seagate Exos 7E8 4TB SAS 128 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SAS HDD for 24x7 Bulk Storage with the ST4000NM0075

The ST4000NM0075 is a 3.5-inch Seagate Exos enterprise HDD engineered for predictable latency and sustained throughput in SAS storage backplanes, pairing 4TB CMR media with 4Kn formatting for modern controller alignment. In virtualized infrastructure, it is typically deployed behind dual-socket x86 server platforms where CPU generation and memory capacity are sized for storage services rather than compute, while the ST4000NM0075 delivers consistent rotational performance at 7200RPM for mixed-read/write bulk tiers.

Designed for PCIe-attached RAID/HBA architectures, the ST4000NM0075 integrates cleanly into SAS expanders and dense JBOD enclosures where PCIe bandwidth is reserved for network and accelerator expansion. Its 4Kn sectors reduce write amplification on properly configured stacks, and CMR recording supports stable rebuild behavior in RAID arrays. Security features including SED and Instant Secure Erase help standardize data lifecycle controls, while Protection Information (PI) supports end-to-end integrity in enterprise storage paths.

Why Choose the ST4000NM0075?

The ST4000NM0075 provides an effective density-to-performance balance for capacity tiers that must stay online under continuous duty cycles. With enterprise-class reliability targets, it scales well from small RAID groups to multi-shelf SAS JBOD deployments, allowing storage architects to expand capacity incrementally without changing the operational model. For platforms where serviceability, predictable rebuild characteristics, and governance controls matter, the ST4000NM0075 is a pragmatic building block.

Seagate designs Exos-class drives around datacentre operational realities, emphasizing controlled acoustics and power profiles, telemetry for fleet management, and durability for 24x7 use. The ST4000NM0075 also supports PowerChoice power management and an integrated humidity sensor to help maintain consistent behavior across varied rack environments.

Key Applications:

• RAID arrays and SAS JBOD capacity expansion
• Virtualization storage pools
• Backup and archive repositories
• SAN/NAS bulk storage tiers
• Data integrity-focused enterprise storage paths
