HDD’s use quite a lot of power and take up a lot of space. I would recommend using SSD’s if you have the budget for it.

Did not buy the 9800X3D

Java? Sorry OP I only download open source software developed with Rust /s

Thought it would be more popular. I’m outnumbered hard

And somehow everyone is still referring to the dead project

M2 isn’t much more expensive than HDDs anymore. It used to be five times times the cost. Now maybe 1.5 to 2 times. And they require a lot less space and no dedicated backplane with seperate power.

Also you need redundancy. A 20TB hdd is very expensive and usually very overkill. Rebuilding them takes very long if you ever have corruption issues, along with other problems.

It’s better to have three smaller drives than a single 20TB one.

Unless you’re running an actual datacenter with cooling and big rack space, m.2 is a likely more worth it these days for a small home NAS.

M2 is getting so cheap that having a drive spinning all day can add up in electricity whereas m2 is a lot more efficient.
