I have a etrex30, I believe it has 2 GB memory. I have a SD card with 4 GB memory.

When I open Garming Base Camp and connect my gps two drives open in the window. My device and "Maps" which is my SD card.

My question, which device should i save my waypoints to and why?

I feel saving waypoints to the GPS would be better than saving to my sd card "Maps" because it would avoid duplicate data.
