I’m new in this space and since I only have a RPi4 for now to play with I’m in need of a personal cloud/ file sharing software with users support that doesn’t hog resources. I remember trying Next Cloud a couple of years ago for an unrelated reason and it slowed my Raspberry to a crawl.
If it has an app/ can be used to mount a drive it’s better.
Sounds like a question for /r/selfhosted
