Google Drive's yearly cost for 2TB is almost equal to monthly payment for Dropbox for the same capacity.
However, Dropbox have some underrated yet very powerful features like Apps and automations. I buy books from plethora of places, and new versions of the products I have are uploaded automatically. I just receive a notification. Same for some fonts and design assets I have. SendOwl leverages this capability for anyone, easily.
Auto organization, a clunky but reliable native Linux application, LANSync, etc. are all good things to have, and they have solved the syncing problem.
Also, Google Drive is a ticking time bomb, because if you accidentally put a file Google doesn't like, you have the risk to lose all your Google access at the middle of the night.
- Dropbox: $119.88 per year for 2TB, plus $39.99 per year for one year version history.
- Google Drive: ~$11.3 per year for 2TB, ~$57 per year for 5TB.
You can also get some free MBs from Microsoft, Proton and so on, and, Dropbox also has a free tier.
