I plan to support SDIO which is about four times faster than SPI since it is a 4-bit bus. SDIO plus multi-block write to contiguous files could be ten times faster than FatFs.
Just to be clear Mr_Arduino, you want support for sdio
bring out all SD lines for SDIO.
Mr_arduino,Why do you want to use this part? It may be great in some product but maybe not in the Arduino hobby world. Why are you laughing at Graynomad? His question is reasonable.A DIP adapter for a 60-pin SDIO part could make some people laugh but not me.
