Users can upload any type of file to Google Docs and convert certain types of files to a Google Docs format -- a Google Doc, Spreadsheet, or Presentation. See the Overview of uploading to Google Docs in the user help center.
Overall 5GB free per account (any kind of documents). You can purchase more. See google.com/settings/storage/ Files that you upload but don’t convert to Google Docs format can be up to 10GB each.
Free storage of 5GB is offered by Google Drive. But my personal favorite is sugarsync for so many reasons.
You better use 4Sync, they give you more free space: 15GB. Uploading limit per document is 2GB for free users
Right now Google drive offering a 5GB free space. And even there is an option to upgrade the limit according to our needs. Find out more: https://www.google.com/settings/storage/?hl=en_GB
I wouldn't want to pay to get 25GB of space. It's not even about the money, it's rather the principle not to pay for services you can use for free
Google provide 5GB, and there are many other providers as well who provide free space. No need to go for buying. Using more than one account in necessity is brilliant.
Oh gee, even though it might be a way out, I wouldn't like to keep different logins and passwords in my head, and remind myself of which files are stored where. Anyway, if you there's a choice between 5Gb and 15Gb, as in 4Sync, for example, I'd choose the second option
