What’s the best & cheapest Google Drive alternative?

Got seriously fed up with how expensive Google Drive has become. The storage plans are getting ridiculous—why am I paying so much just to store my own files? Plus they still scan through my data.

Looking for a cheaper (or free) alternative that still gives me decent storage and easy access across devices. I came across TeraBox, offering 1 TB for free. Has anyone tried this or found other good options? (I’m ready to ditch Google Drive, but I want to make sure I’m not trading one problem for another.
