Sadly the firmware is as yours. Interesting too that the sandisk was also nearly 40, perhaps my Lexar is a fake :-(.
That was my first thought - in virtually all the performance tests I've seen (Rob Galbraith, et. al.) Lexar Pro tends to be at the top. Since there are so many fakes out there, I buy my memory cards from B&H, not ebay, etc.
I know my 1000X cards are extremely quick...
