No matter the actual size, I think you'll definitely need the fastest cards available. Even if a card is specced at 90MB/s that doesn't necessarily mean it won't drop a bit once in a while.
For a GH2 hack with high bitrate you really need a 95MB/s card for example. Even though the actual data is well within 45MB/s.
I don't understand how they are going to do this. If they had the ability to do lossless compression, they would have implemented it on the original BMCC in order to reduce the bandwidth to the SSD.
It is also not clear if this "1.5:1" compression on the BMPC is lossless. If it is not lossless, then whether or not it originated as raw is completely superfluous.
