> The real question is, how much data do we need to store inefficiently, in a way that uses a lot of power and space? This is indeed the critical question, and it's far from being trivial. One issue we all hit is moving the data from the higher tier storage to the cheaper and more efficient one, which requires sync and paying for the transfer most of the time, but also handling two separate access and authorization process, backup and recovery system for data that absolutely needs to be accessible for the few years of legal retention, and can/must completely disappear afterwards. In most orgs I've seen the cost of going through all that complexity is just not worth it, compared to "just" paying for the higher tier storage for the few years long lifetime of the data.
