50gb plan

You won’t find any online storage system that grows over time for the same monthly fee. Not Google drive, not OneDrive, not DropBox, none - all them offer fixed storage allocations for a fixed monthly or annual price. If you later want more storage, you change your plan to one with larger storage And your monthly or annual fee goes up.

Providing the storage costs the provider monthly to offer the service, so they are charging in part to cover their recurring cost of hosting a massive cloud based storage service. But they’re never going to just eat their own bills and give you a wedge of storage for nothing.

50GB is the maximum for all months. You do not get 50 GB more each month. Rather, you are paying to maintain the 50 GB of storage.

You are effectively renting a fixed 50Gb of storage. It will not increase each month.
