I personally would not suggest storage on the tablet. It is to easy to then lose the data if the tablet goes missing, dies, breaks, etc.
You could, however, transfer them to it and then upload them to a cloud account or google account, and save them there. If the tablet has an internet connection. This would give you a safer location for the data.
I would see if the tablet and the camera use the same size cards. If that is the case, you can just take the SD card out of the camera and place it in the tablet to move the files. Just be careful doing this as to not damage the card.
