Low power and reliability is why I want to just use my Mac Mini M4 + DAS as storage solution among 15 people. I am not sold on it because Mac Mini has lots of life in it to be solely devoted to this use case.

I wouldn't be sold on it because macOS is a terrible server OS.

If it can't run linux, it's not going to make a good storage server on the software side of things.

I recently got one as a home server. It’s ludicrously power efficient and so powerful. But it’s a battle getting it to behave, with OS fights at every stage.

It took me a week of fighting to get it to reliably power up, connect to network shares and then start some containers.

How could this be hard?

Which DAS? I looked at that as an option but didn't narrow down a top pick for Thunderbolt JBOD DAS units.

And how much power does the DAS consume?
