D4, 5D3 Memory card performance tests posted

Wow, SDHC is capped at 20MB/s on the 5D3 (figured it would hit 45MB/s. Not any better than cheap Class 6 cards). If I didn't have many other devices that used SHDC I'd return the 95MB/s cards I just bought and replace with CF (which hit 80+MB/s).
I wonder if this is an issue with ALL-I (which should only need ~11.37MB/s max) macroblocking? Perhaps the VBR output is bursty and needs a lot more than 11.37MB/s otherwise it will cut the bitrate.
Need to test this- ordering a fast CF card. Thanks for the info!
[EDIT] Looks like the sweet spot for JPG is 600X (ALL-I is effectively MJPEG). Ordered the Lexar 32GB 600X. If someone has both 600X & 1000X, would be useful to know if they are having any issues with ALL-I macroblocking).[/EDIT]
