I don't know if this is a crazy idea or if it creates scalability issues, but could you craft an algorithm to cold store data for users who do not show a need for instant access, and/or warm up the data when you predict it will be needed? Kind of like a physical logistics company would need to do with distributed warehousing.

Sticking points I see are, 1. If you get it wrong you'll need some form of UX that keeps the users from getting to angry about it. 2. The cost of moving the data between hot/cold storage might make this prohibitive until a much larger scale. 3. User behaviors might not be predictable enough.
