8TB NAS hard drive with AgileArray

The Seagate IronWolf ST8000VN0022 is an 8TB 3.5-inch internal hard drive built for network-attached storage. It spins at 7200 RPM and includes 256MB of cache to serve data quickly in multi-user environments. The drive is optimised for NAS workloads with AgileArray technology for dual-plane balancing and RAID optimisation.

SATA 6.0Gb/s interface limits peak throughput

The drive connects through a SATA 6.0Gb/s interface, which caps the maximum theoretical transfer rate at 6.0Gb/s. Real-world sustained speeds will be lower and depend on the host controller and cable quality. The 7200 RPM spindle speed helps maintain consistent performance during heavy multi-bay traffic.

Standard 3.5-inch bay installation with RV sensors

The bare drive fits a standard 3.5-inch bay using four side or bottom mounting holes and requires a SATA data cable plus a SATA power connector. Rotational vibration sensors help maintain performance in multi-drive chassis, but the drive must be secured firmly to prevent vibration transfer. No mounting rails or screws are included in the bare-drive packaging.

Questions about this item

Which IronWolf capacity should I pick for my NAS?

This model is the 8TB variant; the series scales up to 10TB so choose the capacity that matches your storage budget and bay count.

What does the 7200 RPM speed deliver in a multi-bay NAS?

The 7200 RPM spindle combined with 256MB cache and AgileArray dual-plane balancing keeps latency low during heavy multi-user workloads rated at 180TB per year.

Does the SATA 6.0Gb/s interface limit real-world throughput?

The SATA 6.0Gb/s link caps the burst rate at 6.0Gb/s; sustained transfer will be governed by the 7200 RPM mechanics and 256MB cache rather than the interface ceiling.
