Thinking about switching my storage from cloud to NAS

I’ve been a photographer for some time and usually store a lot of RAW photos and videos. I mostly use cloud storage and also have a few external hard drives. Now I’m running out of space, so I’m thinking about switching to a NAS. It seems like it would make organizing files easier and safer.

I’ve never used one before, so any advice would be appreciated. I’ve looked at brands like Synology, QNAP, and TerraMaster, but I’m not sure what they’re like in real use. I think I’ll need at least 60 TB of storage. For a setup like this, what’s the best way to plan it?
