I've never seen any free cloud service providers provide that much for free. I do enjoy using One Drive and Drop Box whenever I get the chance, based on what I need to share.
My answer is: Use one of the big providers with a decent infrastructure - e. g. OneDrive seems to be reliable and won‘t vanish tomorrow. But encrypt your files locally before uploading them to the cloud. This way, only you will have access, not even the cloud provider or any government.
I don't think any free storage website is this generous. I'd also be very suspicious if someone offered it because I wouldn't trust putting files in there.
As someone who frequently engages with various forms of digital content, I’ve explored a number of cloud storage options. While finding a service offering 750GB to 1TB for free is quite challenging, there are still some great alternatives that provide a decent amount of space without any cost. Google Drive(15GB), OneDrive(5GB), and Dropbox(2GB) are some.
For larger storage needs, it might be worth considering multiple accounts or looking into promotional offers that sometimes provide additional space.
