According to one aspect, a system for managing information objects in dynamic data storage devices including a first data storage device having a plurality of information objects, a second data storage device operatively connectable to an output device for providing at least some of the information objects to at least one user, and at least one processor operatively coupled to the first data storage device and the second data storage device. The at least one processor is configured to automatically divide the plurality of information objects in the first data storage device to form at least one data subdivision based on division criteria, and repeatedly, in response to a dynamic operating condition determine a relevance value of at least one of the data subdivisions in the first data storage device and the second data storage device indicative of the relevance of those data subdivision to the user, and based on the relevance value, perform at least one of loading those data subdivision to the second data storage, or unloading those data subdivision from the second data storage.
