Can someone clarify how this works in terms of data? I see "5GB of persistent data", but that's nowhere near enough for my training data. Is there also a larger amount of non-persistent storage that I can download data to?
The 5GB of persistent data is available for by default for all free accounts running on the free instances. You can easily upgrade your storage up to 1TB by upgrading you subscription within the console. We can also provide up to 4TB by opening a ticket.
