Storage volumes can be much cheaper. For instance, Backblaze B2 will run you around $6/TB/mo, IIRC. And some providers (usually the smaller ones) have discounts for bulk purchases (e.g. a year). Many self hosted apps support cloud storage.

Is it possible to use B2 or DO Spaces as storage for Photoprism?

Sort of. It's not natively supported, but you can use something like s3fs-fuse to mount a S3 compatible storage (like B2) locally and use that. I personally went a different route: Set up Nextcloud, point its primary storage to B2, and then mount a Nextcloud folder (using WebDAV) to my filesystem which I configured as primary storage for Photoprism. That setup was pretty slow, but I also had Nextcloud and Photoprism running on the same VPS which additionally was underpowered for even Photoprism alone. I am now using a separate server for Photoprism and performance is much better
