Abandon SD cards

[tedlanghorst]

SD cards are useful for quickly swapping data, but come with a lot of headaches. Their file structure and protocol was not designed to work well with an 8 bit processor, and the large storage versions currently available have made this even worse. They also draw a lot of power- upwards of 100mA during data shuffling which happens at unpredictable times.

Two alternatives I can think of:

• flash memory (link for comparison and implementation)
• EEProm (link)

Both of these would require additional software to unload the data through the GUI, but I don't think that would be too hard. Might want to resample/average the data before saving in order to unload the data in reasonable time at 115200 baud (~14 kB/s).
