ST8000NM020B Seagate Exos 7E10 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5-inch Nearline SAS Enterprise HDD featuring dual-port secure bulk capacity with the ST8000NM020B

The ST8000NM020B is a 3.5-inch nearline SAS enterprise HDD designed for server and storage-array capacity tiers where predictable latency, sustained throughput, and operational consistency matter more than peak IOPS. In modern CPU-centric platforms, it complements multi-core virtualization hosts and storage controllers by providing economical CMR capacity for large datastores, backup targets, and content repositories while keeping thermals and power within typical rack design envelopes.

Integrated into 12Gb/s SAS backplanes, the ST8000NM020B supports dual-port paths for redundant controllers and multipath architectures, aligning with high-availability designs in shared storage and scale-out enclosures. The drive’s 4Kn native and 512e support simplifies format alignment across mixed fleets, while SED functionality with Seagate Secure enables hardware-based encryption without consuming CPU cycles or PCIe lanes. This makes ST8000NM020B a practical building block for dense pools that also require compliance-ready data-at-rest protection.

Why Choose the ST8000NM020B?

The ST8000NM020B delivers a balanced density-to-reliability profile for nearline SAS tiers, pairing dual-port resiliency with enterprise duty-cycle operation to support continuous service. For architects consolidating capacity behind SAS HBAs or RAID controllers, ST8000NM020B scales cleanly across multi-bay chassis and storage shelves, enabling predictable expansion with consistent fleet behavior.

Seagate engineers the Exos family for 24x7 data center deployment, emphasizing robust error handling, sustained performance under mixed access patterns, and integration with modern SAS ecosystems. With support for T10 DIF and established qualification practices, the ST8000NM020B aligns with enterprise operational standards for data integrity and lifecycle management.

Key Applications:

• Nearline SAS capacity tiers in storage arrays
• Backup and archive repositories
• Virtualization datastores for mixed workloads
• High-density bulk storage pools
