SD & MMC memory cards

  French Chemist 08:08 29 May 04

Not really computer but! I have just bought a digital camera and the book says I can use either SD or MMC cards up to 512MB capacity.What is the difference (except probably the price)? Which would you recommend?

Addendum, came with no card fitted just internal memory.

Basically the cards are "almost" identical although the SD cards were designed to be able to provide higher capacity.

The SD cards also have a higher transfer rate of information which is needed by some items and of course the security aspect.

The MultiMedia Card (MMC) was first on the scene and the Secure Digital (SD) followed - it can transfer data faster, is encrypted (hence the name) and you can also lock it, as with a floppy, to prevent it being overwritten.

Most SD devices such as digital cameras can also use MMC cards but it's not gospel and should be checked with the manual first.

Thanks for the replies. Because my query wasn't computer orientated I didn't do a search on site. Stupid boy!

But it IS - or would be regarded as - computer orientated...:-)
