Uncompressed DNG is fine for a lot of cases and when you offload you can offload via SlimRAWYou can save a great deal. Uncompressed 12bit 4K DCI output of the Sigma fp is ~ 240Mb/sec. That's ~
1 TB/hour. If your use slimRAW, you can copy that uncompressed RAW to two drives simultaneously
(with error checking), compress from 0 to 7:1, and still be undeveloped RAW.
Compression at 7:1 is ~150Mb/s. That's a date rate we were doing 20 years ago. So it's not really
about data rate, the real question is whether or not to stay RAW (including various compression
levels), or bake it with some other compression scheme.
I see no reason to be in a hurry to bake.
The entire workflow, including proxies which slimRAW can create, could be RAW but just at different
compression levels. No doubt efx would want uncompressed, but editing could do with 3:1, mix with
5:1, and producers get the highest number, 7:1.
Many problems could be avoided by everyone staying in the same RAW sandbox.
