The Kurio 7S Android tablet comes with a built in memory of 8GB. These days, with photos, videos and music files especially, this can quickly become inadequate, so being able to expand this is definitely useful.
The 7S does come with a means of increasing the available memory from that which is built-in. This is done using one of the integrated ports, the Micro SD Card.
Using the Micro SD Card, the memory available can be expanded from the initial 8GB up to a total of 40GB, depending on the size of card used.
