Back in a day I got eth Sandisk Extreme 30 MB/s:
http://se.farnell.com/sandisk/sd4903/memory-sd-ext-iii-16gb-30mb-s/dp/1782321?CMP=KNC-GSE-FSE-GEN-KWL
I can reach x 1.3 CBR with this, but 1.4 gets a bit unreliable already.
This one claims to be three times as fast:

Any good/bad experiences, or maybe other brand that let you shoot higher bitrate?
Get a reputable card that does 90-120mbps.
What is the advantage of upping the bit rate like this?

Also... that card is waaay too expensive... something in the middle? Maybe you can do better than 35MB/s, 100Mbit video is only 12.5MB write... so these "30M/15M" cards can't even pull that off. Burst speed lies.

Is there a list anywhere of cards people are using to get the double bitrate? I'd be interested in seeing a list of SDHC/SDXC and CF cards that have been confirmed to work consistently at certain bitrate settings.
I have a Sandisk Extreme 45mb SDHC card. I wonder if I can do the double bitrate on my T3i. Also, was taht test done with a 5d or a T2i/T3i?
Their adapter doesn't support UHS new speed I think. Like 550/600D

Yes. here : http://magiclantern.wikia.com/wiki/Bit_rate

I have it, too. I can go as high as 1.5 with sound, 3.0 without.
Aha, so if you disable audio and Global Draw you can go higher... obviously I have overlooked that detail completely.

In my case its just disable audio.
I was mistaken on the card i had. I have a Sandisk extreme pro 30mb/sec. when i put it to 1.3 i get a meter looking thing ont he right that has 4 or 5 notches. one notch lights up and stays on. It will continually shoot this way, what does the meter mean? would it be better to use the Qscale mode instead?
The meter shows the buffer. When it reach the top the buffer is full and recording stops.
You can choose to not show that bar if wanted.
As it turns out Global Draw has actually no effect on max CBR I can set up... fortunately.

Aren't Scandisk a reputable card maker?
Everyone loves to tout burst speeds and hide sustained write.
Is there a way to set the camera to record mono... and lower the audio bit rate? The only thing I use the on board sound for is to sync to my h4n with plural eyes... if it was mono instead of stereo the audio bit rate bandwidth would halved.. and if the quality could be lowered to something like 128khz or 64khz it might free up some bandwidth for the video.
I'm looking for a card to record at 2.0 with audio... my sandisk 30mb barely does 1.3... I guess I could try a 45mb... also, does the t3i support the uhs-1 speeds?
And thoughts?
Audio has to be recorded separate from the video. It can be done in camera and then the worst that happens is stutters but I think that problem is licked except for extreme cases like 160mbps, etc. Getting a faster card won't help beyond 1.x as the encoder can't keep up with both streams beyond like 60.

If only... Only 48mhz so tops out at 25MB/s My card can only do 20. Maybe newer cards will be able to pull off 25 sustained. Haven't tested and don't have the $200 "pro" card. I got the similarly performing knockoff from patriot.
