SD Card SPI write time

What's the SPI frequency for the FATFileSystem library?
Is it possible to increase it similar to the function spi.frequency(xxx);

If I was wanting to increase the write speed to an SD card, would this be the best way to do it?

Hi Lerche,

Could you provide some details? Interested in seeing how it's done just in case I run into a situation like this in the future.

Thanks for the info, I'll def remember that for future use. I'll also experiment to see what the max speed is.
