Enterprise bulk storage
The Seagate Exos 7E8 ST8000NM001A is an 8 TB SAS hard drive built for enterprise bulk data applications. It suits data centre architects and IT professionals who need reliable 24×7 storage for unstructured data. The 7200 RPM spindle and 256 MB cache support consistent throughput in replicated or RAID multi-drive systems.
Installation and common issues
The 3.5 inch form factor fits standard enterprise drive bays using the SAS 12Gb/s interface. A bare drive is supplied without cables or brackets, so installers must provide compatible SAS backplanes and power connections. The 26.10 mm height matches typical server sleds, yet some compact chassis may not accommodate the 147.00 mm length.
Deciding specification
The SAS 12Gb/s interface determines whether this drive matches the host controller and backplane in the target system. Buyers whose infrastructure uses SATA-only controllers cannot use this drive without an appropriate adapter or HBA.

Questions sur cet article
How can I confirm the ST8000NM001A is operating correctly after installation?
Check the 7200 RPM spindle speed and 4.16 ms average latency in SMART data, verify the SAS 12Gb/s link rate, and run a full surface scan with zero reallocated sectors.
What comes with the bare-drive ST8000NM001A and what must I source separately?
Only the 3.5 inch 8 TB drive is included; you need a SAS 12Gb/s HBA or RAID card, 3.5 inch bay mounting screws, and SAS power and data cables.
Which Exos 7E8 capacity should I choose for a 24×7 bulk-data array?
The 8 TB ST8000NM001A is the maximum capacity in this series, rated for 550 TB per year workload and 2 million hour MTBF.
