... there had been - and you should still be able to get from Samsung - an adapter to plug any USB device or memory into the tablet's input/output socket so you could use USB stick drives, etc. for your media. This greatly increases your tablets storage capacity for media and documents. You probably already know that apps won't run from the external SD card or on a USB stick with the adapter. ...
The adapter being referred to here is called an OTG (On The Go) cable. You can buy it from places other than Samsung, they'll charge an arm & a leg for it. The thing you need to watch out for is that Samsung uses a proprietary connector and not a micro USB like most other tablets.
Here's a listing of the cable on Amazon:
