An 8 TB 3.5″ SATA drive spinning at 7 200 RPM with 256 MB cache, built for 1 to 16-bay NAS enclosures and rated for 300 TB per year
The Seagate Enterprise NAS ST8000NE0001 is an 8TB 3.5-inch internal hard drive that spins at 7200 RPM with a 256MB cache and a SATA 6.0Gb/s interface. It carries a 1.2 million hour MTBF rating and a 300TB-per-year workload rating designed for 1 to 16-bay enclosures. An onboard RV sensor helps sustain performance in vibration-prone multi-drive chassis.
This drive targets administrators building or expanding network-attached storage arrays that run continuously under moderate to heavy write loads. The enterprise-class reliability metrics and rotational vibration tolerance make it a fit for RAID sets in small-to-medium business or enthusiast servers. Buyers who need a quiet desktop archive drive or a laptop upgrade should look elsewhere because the 7200 RPM spindle and enterprise firmware are optimised for multi-drive NAS duty, not low-power or mobile use.
Confirm your NAS or server has a free SATA 6.0Gb/s data port and a matching SATA power connector from the power supply. The bare drive measures 147.00mm long, 101.85mm wide and 26.10mm high, so check that your drive tray or caddy accepts a standard 3.5-inch form factor with those maximum dimensions. Ensure the enclosure provides adequate airflow for a 7200 RPM unit operating within the rated workload envelope.

Yes, the drive uses the 3.5-inch form factor and connects through a standard SATA 6.0Gb/s interface, so the enclosure must provide matching bays and data ports.
The drive spins at 7200 RPM with a 256MB cache; mixing it with slower spindles may cause the array to pace itself to the slowest member during sustained writes.
Run the manufacturer's diagnostic utility to verify SMART attributes, check that the reported 4.16ms average latency and 7200 RPM speed are within spec, and monitor the workload counter against the 300TB-per-year rating.
