I wonder if there is a nptocable difference between a HDD and SSD. Did someone already test it? I run it off a good SSD but wonder if a HDD would be enough.

I use a HDD for my immich instance. I have a feeling it might have made the initial import process quicker (complete google photos dump). However, general usage, I have found zero bottlenecks.
Considering the database itself is relatively small, PostgreSQL could end up largely caching it in memory, so even hosting the DB on an HDD might not feel much slower.
Unless somethkng changed in the last few years, SSDs are much much faster.
They are, but I think the question was more “does the increased speed of an SSD make a practical difference in user experience for immich specifically”
I suspect that the biggest difference would be running the Postgres DB on an SSD where the fast random access is going to make queries significantly faster (unless you have enough ram that Postgres can keep the entire DB in memory where it makes less of a difference).
Putting the actual image storage on SSD might improve latency slightly, but your hard drive is probably already faster than your internet connection so unless you’ve got lots of concurrent users or other things accessing the hard drive a bunch it’ll probably be fast enough.
These are all Reckons without data to back it up, so maybe do some testing
