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?
I won’t comment on the when of it, you have a lot of good answers here already.
But I’d like to add that “performant” is a much lower bar than you think. Gigabit has been fine for my nearly 25 containers to use NFS as their storage, video streaming included.
