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!!).

Cheers

Its my PDA and not my PC, hence this doesnt work....
I know what memory it takes, just not sure what the differences are between them, and the costs.

Thanks for you help

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.

Here's a description of SDIO:

Thanks for that. So is SDIO a form of adding functionality to a device (such as bluetooth and WiFi)? whereas SD and MMC are storage only?

Thanks

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.

Thanks

Yes, but SD is far superior to MMC - that's why it was developed - and the price difference these days over MMC is now very small.

So is the difference between SD and SDII notable (in a PDA) and worth paying the extra money for?

Thanks

SDIO is an input/output interface use of the Secure Digital/MMC socket:

Secure Digital is the memory card.
