The first is persistent data, defined as data that is infrequently accessed and less likely to be modified. The drawback is that your data still lives inside containers, which are not an elegant or super-persistent storage method. Storage architecture has evolved over the decades as compute power and data capacity demands have increased substantially. The Heroku filesystem is ephemeral - that means that any changes to the filesystem whilst the dyno is running only last until that dyno is shut down or restarted.
