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.


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

The key differences is in sound level and weight as the 007 revision is on the higher side.

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.
