Only "reward" for this is possibility to use filesystem and create "real files". I don't think it is much useful. If the SD card was active during the CPU reset, the SD card is unaware that the CPU restarted and gets confused when sent an unexpected command like sd. The Arduino accesses cards using the SPI bus at a maximum speed of 8 MHz with no DMA so you will never get a transfer rate faster than about 500 KB/sec, about half the bus speed. Arduino SD Card Module: Description: Arduino SD Card Module with SPI Interface : Configure & Download; Rating & Comments (1) Tags (0) Alternate Versions . So you're left with almost 31KB free on a regular Arduino Uno. But the limited internal memory of my Arduino (Mega) is making it reset every time. Arduino FAT16/FAT32 exFAT Library.
