ST4000NM007A Seagate Exos 7E8 4TB SAS 256 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SAS HDD for Secure Bulk Storage with the ST4000NM007A

The ST4000NM007A is a 3.5-inch Seagate Exos enterprise HDD engineered for 24x7 server and storage enclosures where predictable throughput and controlled latency matter more than flash-tier IOPS. With 12Gb/s SAS connectivity, the ST4000NM007A integrates cleanly into modern backplanes and SAS HBAs, supporting multipath designs and consistent drive management across scale-out shelves.

Built on CMR recording with 512B native formatting, the ST4000NM007A is optimized for RAID arrays that require stable write behavior, rebuild reliability, and deterministic performance under sustained sequential and mixed workloads. Its 7200 RPM spindle and cache architecture are designed to keep queue handling efficient behind SAS expanders, while power management features help align drive behavior to enclosure thermal and energy policies in dense racks.

Why Choose the ST4000NM007A?

The ST4000NM007A delivers an enterprise-focused balance of capacity density, SAS operational control, and security for bulk tiers that must scale without complicating service workflows. Self-encrypting drive capability with Instant Secure Erase supports rapid decommissioning and compliance-driven data handling, while Protection Information (PI) improves end-to-end integrity in storage stacks that validate data paths.

Seagate designs the Exos platform around data centre reliability targets, including 2.0M-hour MTBF positioning, humidity sensing, and continuous duty operation for multi-drive enclosures. This engineering approach supports predictable lifecycle planning and aligns with standardized service procedures across heterogeneous server and storage fleets.

Key Applications:

• Data centre bulk storage tiers
• RAID arrays and JBOD enclosures
• Enterprise backup repositories
• Archive and retention storage
• Log and telemetry storage pools
