Sorry people, but what is the difference between SD, SDIO and MMC memory? my PDA supports all three but i am unsure which is best/cheapest (have tried looking for it online but cant get the right key words!!).
Secure Digital is an encrypted version of MultiMedia memory and, in most cases, products such as digital cameras using SD memory are also compatible with MMC; however this is not written in stone and your manual will advise.
i read that MMC is slower than SD and that it has less security (?). I was thinking of getting the SD II. its a little xtra but will benefit from speed. dont know if its a massive increase in speed tho.
