ST16000NM007H Seagate Exos X24 16TB SAS 512 MB 3.5" Server HDD

High-Density 3.5-inch SAS Nearline Enterprise HDD engineered for bulk storage nodes with the ST16000NM007H

The ST16000NM007H is a 16TB CMR, helium-sealed 3.5-inch enterprise HDD designed for modern server and JBOD storage tiers where predictable throughput and long duty cycles matter more than low latency. In scale-out architectures, the ST16000NM007H supports sustained sequential performance up to 285MB/s and leverages a 512MB cache to smooth ingest bursts typical of object storage and backup repositories.

Built for SAS backplanes, the ST16000NM007H integrates cleanly into dual-controller designs via dual-port SAS, enabling multipath connectivity for higher availability. It aligns with PCIe-based host platforms through standard SAS HBAs and expanders, preserving compute node flexibility while scaling capacity per U across dense enclosures. Advanced format flexibility (512e or 4Kn) supports consistent sector alignment across mixed OS and hypervisor stacks, reducing migration risk when standardizing large RAID groups.

Why Choose the ST16000NM007H?

The ST16000NM007H delivers a balanced density-to-power profile for 24x7 storage nodes, with enterprise safeguards that reduce operational risk at scale. With hot-plug support and end-to-end data integrity via T10 Protection Information (DIF), the ST16000NM007H is well suited to large RAID arrays and erasure-coded pools where rebuild behavior and data path validation are critical to service continuity.

Seagate engineers the Exos platform for consistent fleet behavior in data centre environments, emphasizing reliability metrics, predictable acoustics/thermals, and interoperability with common SAS expander ecosystems. This approach supports standardized deployment, monitoring, and lifecycle planning across heterogeneous server and storage architectures.

Key Applications:

• Data centre bulk storage tiers
• Scale-out and object storage clusters
• Backup and archive repositories
• RAID arrays in servers and JBOD enclosures
• 24x7 continuous operation storage nodes
