The ability to store application data on external memory cards allows Android device users to expand their storage capacity, providing space for more apps, media files, and documents. This functionality addresses the limitation of fixed internal storage, particularly in devices with lower storage configurations.
Extending storage through external memory provides several advantages. Users can avoid performance slowdowns associated with near-full internal memory. It also reduces the necessity for frequent deletion of applications or media to free up space. Historically, this was a key feature as internal storage options were often limited and expensive. The flexibility to manage application data location offered a cost-effective solution for users.
