Sorry, I gotta call bull on this one. There is no way they could get that kind of data density out of a memory card. This is equivalent to 1,000 of the microdrive I just bought on Friday. Perhaps what they mean is that the interface is capable of addressing up to 2 terabytes. If that's not the case, then 120 megabytes per second of sustained transfer and two TB of storage qualify this as an enterprise server solution.
I think once this starts hitting the market you'll be seeing more sane numbers like 2-4 gigabytes.
