Just wanted to put it out there that we bought eight 64GB Komputerbay CF cards and they all do great recording 1920x1080/24P RAW on the 5D Mark III. I did very long takes. Sometimes it was one take that filled up the card (about 12 minutes). We had no issues.

It was also cool that I could download the cards faster than it took to record a whole card. The setup was a four port eSATA card in a thunderbolt enclosure. I used two RED CF card readers with eSATA and wrote to two OWC two-drive RAIDs. I'm sure there's a more cost efficient solution out there, but with this set up I was able to shoot RAW with two cameras in an interview setting and I was never in danger of filling up the cards.

This is really fun! Thank ML community!!!

I use rawmagic. Then once the CinemaDNG files are in resolve, I change the raw settings for CinemaDNG files to BMD with highlight recovery. Gives a nice flat image and appears to keep all the highlight detail quite well.

Even if it is capped at 160MB/S won't that get us close to hitting 4K?  1920x1080 only requires ~80MB/S
Then if Magic Lantern team can optimize the code even more.  That might be just enough speed.

I like your optimism! Would be really great if they could figure out a way to compress the RAW files while it's in the buffer and then write it out. As it stands, 80MB/sec for 1080P would be 320MB/sec for 4K. 19GB/minute. 1.1TB/hour. That's a lot of data.

My hunch is that the data rate out of the 5DIII will never reach over 167MB/sec as that's what UDMA 7 is rated at. You'd never expect a motherboard with 1.5Gb SATA connection to go over 150MB/sec, or a 3Gb SATA connection to go over 300MB/sec. You'd need a new motherboard to go over those speeds.

Still, if you could reliably record something close to 167MB/sec, that would certain help. Even just having storage capacity go higher than 128GB and also become more affordable would also help and make a CF to SSD adapter marketable.

I don't expect you to show us all the parts you're using or even picture of how you're currently using it, but right now you're just talk. Show us a screen grab of the benchmarks from the camera or upload a raw stream that breaks 120MB/sec and then you'll have our attention. You'll also likely get funded very, very quickly.
