Building slightly on this thread: https://www.truenas.com/community/threads/recommended-4tb-drives-for-truenas-mini-e.92618/
and my comment here: https://www.truenas.com/community/threads/wd-purple.19322/post-675020

I want to upgrade my old 4TB reds to at least 8TB drives. My NAS sits right under my desk, so noise / thermals are high priorities.

Where I live, I can get

WD80EFBX - $190
WD101EFBX - $256
WD120EFBX - $316

all of these drives are listed as 7200 rpm drives on the spec sheet and they clarify (reveal) on the latest spec that even the older EFAX models >6TB have all been 7200RPM the entire time (see here for context)

The spec sheet also reveals that the WD80EFZX are the only true 5400 RPM drive at 8TB - but these are quite old and difficult to find

Does anyone have experience with these EFBX line and how hot they run? It's not worth paying way more for the old fake-5400rpm EFAX drives, right?

I'm leaning towards spending extra for WD120EFBX even though I don't need the capacity right away because they are far quieter than the 10 and 8TB models. Does this equate to far cooler temps in day to day usage?

I have everything in a U-NAS NSC-810A, so the thermals aren't amazing, but aren't terrible. I keep my old WD40EFRX around 35-40C consistently.

I hate to mention seagate given my personal experience with them, but I also notice the ST10000VN0008 hits quite a sweet spot on acoustic performance, so curious if anyone could compare this one as well.

Thanks for any thoughts and happy new year :)
