Seagate Exos 7E8 8TB SATA drive

The Seagate Exos 7E8 is an 8TB enterprise hard drive built for 247 bulk-data workloads. It uses a SATA 6.0Gb/s interface, spins at 7200 RPM and carries a 256MB cache. The 3.5-inch form factor fits standard desktop bays. A 2,000,000-hour MTBF rating underpins its design for continuous operation.

Suits data centres needing high-capacity CMR storage

This drive targets hyperscale and cloud infrastructures that prioritise cost-effective, reliable access to unstructured data. Features such as PowerChoice and PowerBalance technologies help manage power during heavy use. Buyers who need a smaller form factor or a different interface protocol should consider other options.

SATA 6.0Gb/s interface defines compatibility

The drive connects via a standard SATA 6.0Gb/s port, so the host system must provide that interface. Average latency is 4.16ms and the cache is 256MB. Physical dimensions are 4.010in wide by 1.028in high. Verify that your enclosure and controller support this interface before purchase.

Questions about this item

What capacity should I choose for this Exos 7E8 drive?

The model ST8000NM000A is offered in a single 8TB capacity, so there are no alternative sizes to select from.

How does the 7200 RPM speed translate to real-world latency?

The drive runs at 7200 RPM with an average latency of 4.16ms, giving responsive access for bulk enterprise workloads.

What does the SATA 6.0Gb/s interface limit in practice?

The SATA 6.0Gb/s link caps the maximum transfer rate, so sustained throughput will not exceed that bus ceiling.
