You're going to have a hard time beating $2/mo unless you roll it into something else like blackblaze ($100/year for unlimited storage), Microsoft office 365 ($100/year with 1 TB of OneDrive), etc. If your space is going to photos, the speed and responsiveness of Google photos far outpaces some of the alternatives (cough cough OneDrive).
Self hosting is a viable alternative if you're interested in having more control/local storage or if you are interested in this kind of thing and want to do it/dabble in it as a hobby.
I personally built a NAS, which will take far too long to amortize vs just paying $2/mo. I chose this route because I value a local backup and because a NAS can a bit of a lifestyle product. "It can double as a server!". Sounds fun, but I would want to build the thing I host which will also take time so... You could potentially build a NAS that will average out to $2 or less a month if you have spare parts or score some used parts cheap. Odds are that route could also be used for self hosting.
Anyone else remember when Google bragged about never being worried about storage as you watched your storage free count, grow and grow and grow.

I remember. I'm also paying Google $2 a month for 100gb. Fucking bastards. But can you point me to 100GB for less?
