That sounds very expensive for 8TB of storage. I should think you could build a modest NAS for half that. Alternatively, buy two Western Digital My Books to get more space + redundancy.
I didn't want a NAS. I wanted a linux machine to experiment with docker and setup photoprism. I am self-hosting ~20 containers so far. It has 32GB RAM and pretty good CPU to experiment and run different workflows in the containers. I noted it could be done cheaper but that is not my goal. Can always add external storage.
