ST10000NM020G Seagate Exos X18 10TB SATA 256 MB 3.5" Consumer HDD

High-Capacity 3.5-inch Enterprise SATA HDD featuring Nearline Density and SED Security with the ST10000NM020G

The ST10000NM020G is a 10TB 3.5-inch enterprise nearline HDD engineered for capacity-tier nodes where CPU and GPU resources are primarily allocated to data services, backup pipelines, or analytics pre-processing rather than local compute acceleration. In modern x86 server platforms, the drive complements high-core-count CPU generations and large DDR4/DDR5 memory footprints by providing predictable bulk storage without consuming PCIe lanes that are typically reserved for NVMe, NICs, or accelerators.

Using a SATA interface and 7200RPM CMR recording, the ST10000NM020G supports stable sustained write behavior for rebuilds and long sequential jobs in JBOD enclosures and scale-out storage shelves. Advanced Format 512e/4Kn options simplify alignment with contemporary RAID/HBA controllers, while hot-plug capable integration supports serviceability in dense nearline arrays. Hardware SED encryption is implemented at the drive level to reduce CPU overhead compared to software encryption, and it aligns with common key-management practices in enterprise environments.

Why Choose the ST10000NM020G?

The ST10000NM020G delivers an efficient density-to-power profile for capacity-first architectures, enabling higher usable TB per rack unit while keeping expansion focused on standard SATA backplanes. With 2.5M hours MTBF and enterprise thermal tolerance, the ST10000NM020G is suited to large fleets where reliability, predictable behavior, and repeatable deployment at scale are essential.

Seagate designs the Exos platform with an engineering focus on sustained 24/7 workloads, consistent firmware behavior across deployments, and compatibility with modern data center standards for security, serviceability, and lifecycle management.

Key Applications:

• Nearline capacity tiers in scale-out storage
• JBOD-based bulk data repositories
• Backup and archival pools
• High-capacity RAID arrays in servers
• Cold and warm data lakes
