I  noticed offerings of  SD and SDC(compatible) ... on the C-ONE Technology Corp site, the IP side of  Pretec if you read a previous post.

SDC offering  is not noted on the Pretec site..the only thing I see relating to compatible is SuperSD

Will their SDC offering work in my Canon SD630?...lol 

"Low battery consumption to maximize battery life in small portable devices"

This designation is most often noted with regard to Pretec SD memory....what makes there SD more significant than other manufactures with regard to power consumption?

Microcontroller...cache...memory configuration?

Would both of these issues be considerations DM is looking at?
