Hi @steve4,
A couple of services that odrive supports, aside from Amazon Drive, that fit your criteria:
-
Microsoft offers a 365 Home subscription for $100/year. This gives 5 user licenses and each user gets 1TB of storage. You can use odrive to link the 5 accounts, yielding a total of 5TB of storage, albeit in separate folders within the odrive folder. Their mobile offering is decent and have versioning for Office file formats. You also get Office 365
-
Google Drive has a 2TB plan at $20/month. They have a decent mobile app and they support versioning and file history auditing.
