The amount of internal memory that a tablet has is important. Even though memory card slots can be used to expand the available storage, which is useful for downloaded and user-created content, especially as the resolution of tablet cameras improves, the operating system and at least a portion of every app will use up part of the tablet’s internal memory. Low internal memory means that there is less available for the user, as it will already be taken up by necessary software.
The Sannuo 10.1″ Kids Tablet has 16 gigabytes of internal memory, which is about standard for currently available children’s tablets; some have more but few new children’s tablets have less.
