Dual Card-Slot Workflow?

[bfmawhinney]

The 5Diii is my first camera with dual card slots, and I'm trying to figure out my work flow. Here's my thought process:

I'll record jpegs on one card and RAW on another for my "everyday shooting." That way I can upload my jpegs into Lightroom 4 and keep my snapshots with minimal storage usage, and then pull out the few that I'd want to really process and potentially enlarge, and then grab those RAW files.

Questions: If this workflow makes sense, do you recommend CF vs SD for RAW (and how about for video, SD or CF?)? Does Lightroom 4 have a way to convert the original RAW files to jpeg rather than just exporting and making duplicates so that I could only shoot RAW and then just easily convert my snapshots to jpeg for storage purposes?

(CF - SanDisk Extreme, 16GBs, 60MB/s //// SD - Trascend 32GB, class 10)

Does this even make sense?

Make sure you get fast SD/CF cards. (45MB/s? not sure exactly how fast is "enough") I tried out this exact setup (CF: raw, SD: jpeg) and once the buffer filled up (approx 7 frames, I think), it took a second or two to clear the buffer enough to shoot again. Definitely more sluggish than it should be.. Removing my slow SD card improved things dramatically, and my CF's are only 30MB/s or 45MB/s - definitely not the fastest. Now I'm shopping for a decent SD card.

Thanks for the insight, I'll try a few set-ups out...

I make a jpeg copy on the SD card, but its just a emergency copy, and is never used, but is there in the event I were to lose my raw image card. I have a 64 GB Sandisk SDXC 30mb/sec SD card, its plenty fast for me, but I do not ever use the high speed fps for more than three or 4 shots without pausing. The SD card never leaves the camera.

basically the same as this for normal use
I have some 32GB sandisk 45 mb/s SD cards
for my CF cards I use transcend 400x 32GB cards, probably the best value for money
for a wedding though i will shoot raw to both the CF and SD for added protection
