Manufacturer description
Built for 8-bay NAS enclosures, the Seagate IronWolf 3TB (ST3000VN007) is a CMR 3.5-inch SATA 6Gb/s drive spinning at 5900 RPM with 64MB of cache and sustained transfer speeds up to 180MB/s. Because it uses CMR rather than SMR recording, it handles the sustained random writes that RAID rebuilds and multi-user file shares demand without the write-cliff behavior that plagues shingled drives in arrays. Seagate rates the IronWolf line at 1M hours MTBF, and the integrated IronWolf Health Management system reports drive health directly through supported Synology, QNAP, and Asustor NAS software so…
SpecPicks Verdict
SpecPicks scored Seagate IronWolf 3TB NAS Internal Hard Drive HDD using a rating × review-volume × price-fit model applied to published specs and reviews across the nas & home servers category. Seagate's nas & home servers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for nas & home servers of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Seagate rates this drive for NAS enclosures with up to 8 bays, covering most home and small-business units from Synology, QNAP, and Asustor.
What warranty comes with this drive?
Seagate includes a 3-year limited warranty plus a three-year Rescue Data Recovery service subscription. Check the product listing for current terms in your region.
How fast is the Seagate IronWolf 3TB?
It spins at 5900 RPM with a 64MB cache on a SATA 6Gb/s interface, with sustained transfer speeds up to 180MB/s — enough to saturate a gigabit network link.
Is the IronWolf 3TB reliable enough for a RAID array?
Seagate rates it at 1M hours MTBF, and IronWolf Health Management surfaces warnings inside supported NAS software.
