One of my NAS drives failed, so was looking for a replacement 3TB, and these seem pretty good. I'm not sure if these are optimised for NAS, or gaming or what, but I think drives are the same, with firmware tweaks. Anyway A$112 seems like a deal.

The ironwolf drives are NAS rated, these are not. Ironwolf drives have the warranty and different operating specifications suited to 24/7 environments.
