You get 2 SD cards and a Wifi dongle, but you can upgrade them. It HAS to ship with the SD cards because that's where the code is to run the game and upgrade it with new code.

Upgrading the wifi dongle with a good one (antenna helps, too) will give you more range.

Upgrading the main SD card will be more reliable and about 6 second faster boot.

It's a microSD at the bottom of the board, below the CPU. I *believe* it is a scratch storage of sorts, used for unpacking updates. I wouldn't worry about that one unless it fails since it's used much less often.
