Interface SD Card through GPIO on DE0-Nano

I would like to interface my Terasic DE0-Nano running a Cyclone IV with an external SD card that I will attach to a circuit board that will also interface with the GPIO headers on the DE0. I'm pullin...

Thanks for your reply, Xaui. The reason for the dual access to the SD card is because the experiment requires remote recording of multi-channeled PDM microphone data over an extended period of time sampled at a relatively high frequency. I don't want/need to access the data in real time, I just want to be able to periodically pull data in between experiments. However, I do realize that dual access to an SD card without physically replacing the card is not trivial. Do you have any other suggestions?
