Product overview

Seagate’s IronWolf 12TB (ST12000VN0008) launched on April 17, 2019 as a refresh of the IronWolf NAS HDD family in the Guardian Series. It’s a 3.5-inch SATA 6 Gb/s, helium‑sealed CMR drive with 7200 RPM and 256 MB cache, built for 1–8‑bay NAS with RV sensors, 24×7 operation, and a 180 TB/year workload rating. Datasheet sustained throughput is about 210 MB/s.

Tier: budget (capacity‑first HDD). It exists to deliver dependable, always‑on mass storage for home/SOHO NAS at lower cost than enterprise lines. Well‑suited to large media libraries, backups, and a shared game library; not ideal as an OS drive or for heavy random‑IO workloads. Unique: integrates IronWolf Health Management in supported NAS firmware.
