Expandable storage refers to the ability to increase the storage capacity of a device, such as a smartphone, tablet, or laptop. This is typically achieved by using external memory cards, like microSD cards, or external hard drives. Users can add more space for files, photos, and apps without needing to replace the device itself. Many devices come with built-in storage, but it may not be sufficient for everyone’s needs. Expandable storage offers a flexible solution, allowing users to manage their data more effectively. This feature is especially useful for those who store large amounts of media, such as videos and music.
