Good to hear the new card readers solved your issue and the D4 lives to shoot again....
I also just tried a similar test with copying a bunch of pics from the D800 to and from my Sandisk Extreme Pro CF UDMA7 90mb/s card and was getting writes to the card, from my SSD internal hard drive, at about 59mb/s and copying from CF to SSD at about 51mb/s. So the data looks like this:
Write speed: ~68mb/s Read speed: ~52mb/s
Sandisk Extreme Pro:
Write Speed: ~59mb/s Read speed: ~51mb/s
Very unscientific test, but it does show the 1000x cards to be just a little faster which would explain results that I see from this site:
