Ok, I was mistaken and multiplexing isn't used. I thought that I
read years ago that some PDAs which used both MMC and SD cards had a
faster data rate due to using a wider data bus, but that's probably
not true. I doubt that the difference was that SD cards transferred
data on multiple serial lines, but the way I'm going today, I'd
better not assume anything else. :)
With SD using serial data transfer, it may be a point in favor of
CF cards, which should then have the potential to have a much
greater data transfer rate. For me though, SD is fast enough. But
then I use them in still cameras, not video cameras. I saw one
demonstrated on TV today that had 60GB of internal memory, said to
be enough for 2 hours of video at its finest resolution. They
showed a 16GB card for it that looked like SD (I didn't hear that
part of the presentation). The camera might have been a Canon.
