Hi, Windows can read and write to SD Card ! :-) 

Do you mean that you want a board able to read and write to SD Card ? 

 

 

I think the sd card should be readable by windows, shouldn't it ? 

If so, it implies a FAT (File Allocation Table) and a "driver". 

 

Altera tutorials contains examples to read from SD Card. 

 

There is a MP3 touchscreen player built with an Altera dev kit. Find it in this forum. 

 

It is not trivial for a beginner. 

 

Look at opencores.org 

 

Free or opensource SD CARD drivers you can find have poor performance because they use only one data signal while SD CARD has 4 data signals 

There are also drivers (Elcamino, ...) that you can pay thousand dollars to do it.
