You need this: Sandisk Extreme Pro 64 GB 95 MB/s http://www.amazon.com/gp/product/B007NDL54C/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
You're Physics are either wrong or Magic Lantern isn't telling us everything. I use a Sandisk Extreme Pro 64 GB 95 MB/s. It doubled the recording time compared to my Sandisk 45 MB/s Card. Also note, I disable Audio. The Video shows the resolution so what is there to lie about.

My samsung sdhc has same speed as sandisk extreme pro (i tested both in cardreader and in ML) but i cant get your results. What kind of dark magic do you use, and how much virgins blood do you sacrifice to earn such raw speed?

Correction, only one person says he got 40+ seconds with 1792 resolution
I doubt that
Got a 6d for more then a year and two fast Sandisks cards...never had more then 14 seconds of 1792x 750 resolution or 17 seconds of 1728 x 724 resolution...
That is 25 fps MLV's with audio enabled.
2.39 aspect ratio is our lifesaver
You can calculate the whole thing:
Your precious 6d SD card slot can write about 40MB/s max and the buffer is about 255MB.
1792 x 750 x 25FPS x 14bit /8 (Bits to bytes) /1.000.000(bytes to Megabytes) = 59 MB/second... So if your SD can write out 40MB/s your buffer fills up with 19MB/s
255MB buffer / 19MB = 13 seconds of video -> boom buffer full
It's called physics
BTW
To enable the 255MB buffer you must activate in the ML raw menu -> the SRM memory hack/buffer option
Yes, i made this calculations too, but cant get even 13 secs. I try all from this thread and also activate hack in ml menu, but still it shows 155mb of buffer and only 7 secs of raw. I can shoot only 24 fps 720p continuously. And i shoot without audio.

As a 6D user, at the moment i can record RAW video at 1792 x 750 x 23.987FPS x 14bit to a maximum of 20 sec. than it skips frame.. But my guess is that it has to do that maybe i was shooting particularl dark subjects?
20 sec is nice too. What kind of card do you use?
