Re: Do SDHC cards really work?

Hi Craig, thanks for your kind words. As you know I have not been very active on forums. We at MxM put a lot of energy into the development of the MxM card. So the knowledge we have acquired over the past few months is staggering. Just to summarise, we've done 3,500 hours of recording on 16GB and 32GB memory cards. We tested and are still testing memory cards and it comes to the point that consumers have to settle for something that is reliable and reasonably priced rather than to go for cheap and uncertain. I will be slowly releasing information to the public through here if anyone is interested.
To start with, in regards to over cranking, the behaviour of Slot A to B on the camera is different to the point that the difference is roughly 4 to 5 fps. eg. If you use Slot B to over crank, you might get max 50 fps and if you use the same card with the same memory in Slot A you'll get 54 fps. Obviously not all cameras are made equal so in some batches it might be reversed.
We've done a lot of testing on Silicone Power 32GB and it appears to work very well, but even they keep changing their firmware, but it works and the sample card I have works very well, but I can't guarantee the stock in the shop will be the same unfortunately.
In regards to ATP ProMax, we first started testing on our older cards in April, and the 16GB works fantastically to the point that one of our customers took it to the Himalayans and filmed in minus zero temperatures and got great footage with no issues. That's the reason we then started to develop the MxM card with it so it could work with 32GB as the old chipset was not very stable back then but 32GB now with the new MxM card is equally reliable as I've never lost any footage on ATP ProMax, nor have my customers.
Finally not to forget or overlook the fact that we also test Hoodman's memory cards extensively with our adapters and they are manufactured to the highest standard.
We really took time and spent a lot of effort in working out the relationship between Sony's camera | our MxM adapter and memory cards and I must say we are almost 99% there...
