Update - 1D X results:

-Lexar 95 145MB/s (according to the package) write: 51 frames
-Sandisk 90MB/s write: 52 frames
-Sandisk 150MB/s write: 57 frames

This is interesting and shows that the buffer size or the interface in the 1DX is different than the 5DIII, but all of the results are excellent given that the Sandisk 1067x card is delivering a burst depth of 35 RAW frames in the 5DIII (vs. the rated 18) and 57 RAW frames in the 1D X (vs. the rated 38).  RAW+JPEG to the two Sandisk cards topped out at 15 frames, FYI.

Bottom line - the fastest Sandisk cards rock the 5DIII, while the older Sandisk cards are a great deal for the 1D X.  Lexar doesn't quite ive up to their specs, at least in these two Canons.

Also, on a personal note, the 1D X may only be 2x faster on paper, but the thing sounds about 20x faster than the 5DIII.  I can't wait to shoot with it...

Interesting but how did you measure 51 or 57 frames?

Several pages back, I outlined how I did the testing (see below) - the 1D X test was done the same way (RAW files @12FPS, not JPEG @14FPS) - and while they are all black frames, it's a good way to be consistent.  In real world shooting, I found that the buffer fills up faster as the frames are larger, as you'd expect from real photos...

Camera settings
-5DIII with battery grip - 2 fully charged batteries (grip doesn't matter)
-Freshly in-camera formatted CF cards
-ISO 100, 1/8000s, body cap (so f/0, manual focus)
-ALO, High ISO NR, vignette removal, CA correction OFF
-RAW
-High Speed Drive

Test
-Depress shutter fully until the camera slows
-Wait for buffer write to finish
-Press image review - look at # of images, subtracting the extra frame that indicated the buffer was full
