Built for multi-bay NAS

The Seagate IronWolf ST8000VN0022 is an 8TB 3.5-inch internal hard drive spinning at 7200 RPM with a 256MB cache. It uses the SATA 6.0Gb/s interface and is optimised for network-attached storage systems that run around the clock. The drive carries a workload rating of 180TB per year and a 1M-hour MTBF figure.

Fits standard 3.5-inch bays

The bare drive measures 146.99mm long, 101.85mm wide and 26.11mm high, so it slots into any tray that accepts a 3.5-inch form factor. AgileArray firmware adds dual-plane balancing and rotational-vibration sensors to keep performance steady in multi-drive enclosures. IronWolf Health Management monitors drive health and integrates with compatible NAS operating systems.

Suits always-on NAS arrays

Buyers building or expanding a RAID array with up to 16TB per bay will find the 24×7 rating and RV sensors a direct match. Shoppers who need a portable external drive, a laptop upgrade or a boot drive for a single desktop should look elsewhere because the firmware and physical size target multi-bay appliances.

Questions about this item

How much data can the ST8000VN0022 write per year before reliability drops?

The drive is rated for a workload rate of 180 TB per year, which is the sustained write limit Seagate specifies for this IronWolf model.

What are the power draw and noise figures when the drive runs 24×7?

Seagate does not publish idle or active power consumption or acoustic levels for the ST8000VN0022, so exact heat and noise numbers are unavailable.

Does the ST8000VN0022 need a special NAS cage or controller to work?

It uses a standard SATA 6.0 Gb/s interface and 3.5" form factor, so any NAS bay or desktop cage with a SATA data and power connection will support it.
