I’ve been selfhosting a while. I run around 15 distinct services in docker containers, all on a single machine with a medium sized disk. It’s a small form factor, and I recently had to add space, so I’ve attached an external USB storage device.
It feels clunky.
At what point does a performant SAN/NAS make sense more than local storage? When did you make the jump?
When you need the data on more than one machine.
Honestly this is the simple answer. My partner and I needed to access the same files often enough that we started using a NAS before I even got into self hosting. In fact, really, the NAS was my gateway drug haha.
