Compact Flash(CF) versus Secure Digital (SD) memory cards

Hi All,
Is there any read and write speed difference between Compact Flash(CF) versus Secure Digital (SD) memory cards?
Do you know any AVR and/or PIC code to read/write (as fast as possible) to CF and SD?
Is there small/tiny unit which accepts a RS232 input to read and write to CF and SD?
Thanks
Miem

Hi,
Have a look at AVR-Dos. It's part of Bascom AVR (www.mcselec.com and http://members.aon.at/voegel )
