ST16000NM004G Seagate Exos X16 16TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5" Enterprise SAS HDD featuring helium-sealed CMR capacity with the ST16000NM004G

The ST16000NM004G is a 16TB Seagate Exos X16 3.5" internal enterprise HDD designed for SAS backplanes in rack servers, JBOD shelves, and RAID controllers where sustained throughput and predictable latency matter more than burst performance. In modern CPU platforms with large DRAM footprints, the ST16000NM004G supports capacity-driven tiers that offload colder datasets from PCIe/NVMe pools while maintaining deterministic block access under multi-initiator storage stacks.

Built around 12Gb/s SAS, the ST16000NM004G integrates cleanly into PCIe-attached HBAs/RAID adapters and expands linearly in dense enclosures, enabling scale-out object, file, and backup architectures. CMR recording and 7200 RPM operation provide consistent write behavior for rebuild and scrub cycles, while 512e/4Kn options with adjustable logical sector size simplify alignment across mixed operating systems and hypervisor storage appliances.

Why Choose the ST16000NM004G?

The ST16000NM004G delivers an enterprise-friendly density-to-bay ratio for capacity nodes while keeping operational risk controlled through SAS protocol robustness and sustained performance characteristics suited to parity RAID and erasure-coded clusters. Its architecture targets 24/7 duty cycles in multi-drive environments, supporting scalable growth from a single shelf to multi-petabyte pools with consistent manageability.

Seagate engineers the Exos platform around measurable reliability and serviceability for data centres, combining helium-filled mechanics, a humidity sensor, and a 2.5M-hour MTBF design goal. Features such as PowerChoice and PowerBalance align the drive with modern energy-governance standards without compromising predictable storage behavior.

Key Applications:

• SAS JBOD and RAID capacity expansion
• Scale-out file and object storage nodes
• Backup, archive, and compliance retention tiers
• PI-enabled data integrity environments
• Secure decommissioning workflows using ISE
