This board can hold 1 multimedia card.
This will allow you to install a 32meg card and store all kinds of data.
This is a smart peripheral in that it has a controller chip built in to control the memory card.
This board can be programmed as a data logger that will read the sensor board directly and store the data in the memory. This should be capable of 1kHz sampling rates. And with a 32meg card it would record both 12bit channels for over 2 hours!
Another great thing about this design is that you can remove the MMC card from it and plug it into a USB card reader and download the data in no time at all. Also you can replace it if it becomes full.
