I have and love my self-hosted immich install. If self-hosted could also use S3 storage, that allows me to use Garage (https://git.deuxfleurs.fr/Deuxfleurs/garage) , which also lets me play games with growable/redundant storage on a pile of second-hand hard drives. IIRC it can only use a mounted block device at the moment, (unless there is a nfs-exposed s3 translator ....)

A lot of existing tooling supports the s3 protocol, so it would simplify the storage picture (no pun intended).
