ST8000NM018B Seagate Exos 7E10 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5" Enterprise SAS HDD for Tiered Storage and RAID Reliability with the ST8000NM018B

The ST8000NM018B is an 8TB 3.5" internal enterprise HDD designed for server and storage platforms where the CPU and memory resources of modern controllers are leveraged to drive predictable bulk capacity at scale. In SAN/NAS tiers and data centre nodes, the ST8000NM018B integrates cleanly behind SAS HBAs and RAID controllers, supporting dual-port connectivity for high-availability backplanes and redundant paths.

For expansion architectures using SAS fabrics and dense enclosures, the ST8000NM018B provides CMR recording behaviour suited to sustained writes in rebuild and replication windows. Advanced Format support (512e/4Kn) and T10 DIF capability align with enterprise integrity models, while 7200 RPM operation and 256MB cache help stabilize queue depth under mixed sequential throughput and transactional metadata activity. This makes the ST8000NM018B a pragmatic choice for capacity pools that must remain serviceable during maintenance, migration, and RAID recovery operations.

Why Choose the ST8000NM018B?

The ST8000NM018B delivers a balanced density-to-performance profile for large drive counts, with dual-port SAS enabling resilient multipath designs in shared storage and clustered server topologies. With an MTBF rating of 2.0M hours and 24x7 duty alignment, the ST8000NM018B supports predictable lifecycle planning, simplifies fleet standardisation, and scales efficiently from small RAID groups to multi-shelf capacity tiers.

Seagate engineering for the Exos line prioritises consistent enterprise firmware behaviour, long-duration operational stability, and integration with modern data centre standards for vibration, thermal management, and integrity features demanded by storage controllers and enclosure vendors.

Key Applications:

• Data centre server storage tiers
• SAN/NAS capacity pools
• Backup and archive repositories
• RAID arrays for enterprise applications
• Bulk object and file storage
