Many thanks to Lars, Joseph & others who've contributed their experiences/tests & benchmarks in this thread.. very helpful stuff & you just saved me some money.
I found it interesting that though the Lexar 1000x is very similar to the Lexar 1066x. the 1000x cards are only rated as 150mb max read speed, 95mb max write speed, whereas the 1066x cards are rated as 160mb max read speed, 150mb max write speed.
If I had to deduce from those numbers alone, I'd likely think the 1066x cards could crank out a ton more images on the 1DX, which doesn't seem to be the case.
