Just get a NAS and host your own stuff. Nextcloud is quite good, but pretty slow. Seafile is also quite good, is faster, but with less functionality.

Otherwise:

Free:

• pCloud. But i heard they shut down accounts because of copyright shit, but many cloud providers have something like that in their TOS. They also have often lifetime offers like this one: https://stacksocial.com/sales/pcloud-premium-lifetime-subscription

Paid:

• Hetzner Storage Share, if you live in Europe. A managed Nextcloud instance with 1TB space for like 5 bucks a month.

I thought Dropbox was just storage, do they do anything else? You can get any cloud storage or your own. I run a NAS at home and use that.

Nextcloud has replaced Dropbox completely for me, and added functionality too. Everyone says it's too slow but recent major updates have overhauled its speed and I never had any issues to begin with, so whatever.

Box.com and iCloud. I believe Google, Amazon, and Microsoft all have similar services although I've not tried it. It might be worth checking out Amazon Drive if you're already paying for Prime.

Or do what everyone else is suggesting and roll your own.

Host your own.
