SPI SD card write speed tweaks

UP.
I also noticed that the writing time isn`t realyl affected by how much stuff i write. It takes 40ms to write "asd linea di valori che bello la nonna ha fatto la pasta" and it takes 45ms to write that thing TEN TIMES, assuming that it is provided to the write function all at once, in pretty long array. If I call the write function ten times seprately it takes 400ms to write it ten times. May someone please explain this to me? (and move the thread in the "storage section" if you think it is the case to do so)
Cheers! :wink:
