Disclosure: The Ironwolf 12TB NAS HDD is loaned by Seagate

This is the Ironwolf 12TB NAS mechanical hard drive, the non-pro variant of the previously reviewed NAS HDD from Seagate. I’ve already summarized the differences between the Ironwolf and Ironwolf Pro series, not much different from WD Red and RED Pro.

About the IronWolf and the IronWolf Pro series NAS HDDs…

We’ve had NAS HDDs for a while and it is a common choice for those who archive data, content creators who want large storage for RAW images and videos, folks with network storage for SOHO or small enterprise services. WD has the Red and the Red Pro series, while Seagate has its IronWolf and IronWolf Pro series.

This is the Seagate IronWolf Pro NAS HDD with 10 TB storage capacity. Seagate uses AgileArray technology these HDDs which is optimized to work in always-on and multi-user access situations on RAID-enabled NAS. The word ‘Pro’ applies to NAS drives up to 16 HDDs with higher mean time between failures and other optimization. Warranty period differs between the variants as IronWolf honours three years warranty while IronWolf Pro honours five years warranty and two-year cover for data recovery services with registration. Additionally, the IronWolf Pro have rotational vibration sensors which work by spreading the vibration throughout its casing. Therefore, any possible issue due to system vibration is reduced dramatically.


This is the 12TB Ironwolf NAS HDD ST12000VN0007 which also has another variant ST12000VN0008.

HDD Sub-Components

The IronWolf 12TB NAS HDD carries a three-year warranty. Nothing has changed in terms of controllers and motors on the PCB, with Seagate still using a SMOOTH motor controller and Avago controller with a 256MB Cache. We’re testing the 007 variant.

  1. ST12000VN0008 – 18dB, yet no review bother to check that.
