A computing device includes a primary content storage machine configured to selectively store one or more content portions of a digital content item, such as game portions of a video game. The computing device is configured to determine a size of a dynamically changing content access window including one or more content portions usable to provide an above-threshold user experience, such as uninterrupted game play, based on a current access position of the digital content item or video game and historical user-specific play patterns or game play consumption rates of different users. The computing device is configured to dynamically load the primary content storage machine with the content portions or game portions corresponding to the content access window and dynamically unload the content or game portions outside of the content access window from the primary content storage machine.
