| I'm thinking about buying a big fat SD Card for my camera, but I'd like to use it for other things too. However, reading about the SD Card it sounds like it has some kind of protection against putting music on it. Is this the case? Is MMC Card the answer? I'm very confused about the relation between the two. |

I can't remember exactly what it was that I heard about MMC that wasn't really that cool. I think it was that because it is considered a secondary format to the SD, most cameras have their accessing speeds slightly lower to them (even though 150x MMC cards came out a couple of months before the 150x SD cards did, suggesting a VHS vs Beta type scenario), which means you are unable to record video to MMC. I believe I read this in my S2 manual, but I don't have time to check on that right now. You should check the manual of your Sony and check with the company if this is important to you. I don't know if it also affects the writespeed when considering burst mode as well. Worth an email to Sony at the very least.
I have a 1GB SD card. I have never heard about any sort of protection against putting music on it. I would assume this is pretty unlikely. I use my card for photos and music right now, swapping between my camera, my PDA and my mp3 player with SD card slot. I will ask next time I'm in the shop. I'm considering picking up a 4GB 150x SD in a few weeks. Currently the price is around 4200NT dollars which is around 130 US.
It would require software to check for protected music. If you are playing in an MP3 player, it would probably say something about DRM on the box. I also believe that if you are using WMP9 on PDA, you don't run into this problem either.
SD cards have read/write protection built in by a slider on the side. I am sure some people use it, but I never have. |

| Most SD cards are faster then MMC cards. MMC cards are really rare, so it's quite difficult to find them. If you are in a pitch they will work for most SD card equipped cameras and devices. |

| What I saw at the last computer show in Taipei led me to believe that MMC is trying to make a bit of a comeback due to the strong showing in large cards that were actually faster than the SD versions. However, in the open market, I see things have not really changed much. |

MMC cards are thinner than SD cards. There are some gadgets that take MMC only as their slot is too thin to take an SD card, but these are quite rare. MMC are harder to find and often slower - check out the speed of the individual card you are going to buy.
The only other difference is that SDs have a little slider thingi that acts as a write protect switch i.e. prevents you erasing or saving stuff on the card if clicked on. Not a big deal to me, have knocked it into the locked position accidentally a couple of times, annoying but not enough to put me off SD.
Both are basically empty storage space and anything can be saved onto them. I an confirm that MMC will definitely play video, had a phone that would play videos and managed to compress a whole James Bond movie so it would fit on my 128Mb MMC. Of course it was low resolution so it would play on the phone but it was kinda cool....
Conclusion: unless you are likely to buy a gadget that only takes MMC, SD is fine and easier to find. If you do buy MMC make sure you get a nice fast card! |

NO... the "protection" you were reading about is that on the body of the SDcard, there is a little switch that you can push to "lock" the SDcard from accidental erasure or writing. that's all.
I would prefer an SD card over an MMC. I dont really know why. |
