Hi Ben
This is not so good news now...
but that might be a reason to increase the speed from the existing FAT. This works very well. But not so fast.....
I do not need extremely fast speed, but 1Mbit / second with an SPI bus of 50Mhz.
It's all about writing speed. reading would not necessarily be faster.
Perhaps we could improve with larger buffer and blockwise write something.
I hope if we would write 1024 * 512 block with a new command.
