I guess I would be willing to spend an additional $16 for a CFE card with 5 times the write speed of the SD after spending $5-6k for a camera. At very least the cost difference would not be a factor in system decision.

I agree with you in theory, but $16 extra seems a bit optimistic for the kind of speed you're talking about. From what I've seen the CFExpress cards that actually perform as rated are still quite expensive.

The $16 difference for an incredible step up in performance is what was quoted in the post to which I responded, two Sandisk 128GB cards at B&H;

”128GB 1400MB/s write Sandisk Extreme Pro CFExpress cards go for $180 at B&H Photo

128GB 260MB/s write Sandisk Extreme Pro UHS-II cards go for $164 at B&H Photo“

My point is you can get SD cards for far cheaper than CFE cards, but if you want top levels of SD card performance the prices are similar to CFE, but the performance is far behind.

The issue is that $180 Sandisk CFExpress card is not going to deliver anywhere close to 1400 MB/s, Sandisk's CFExpress card ratings are, unfortunately, complete garbage. To actually get speeds like that you're looking at cards like the ProGrade Cobalt which start at $400. As a reference, in the R5, the Sandisk Extreme Pro CFExpress gives an actual write speed of ~335 MB/s while the $100 128GB Kingston V90 gives an actual write speed of ~215 MB/s. Certainly an advantage to the Sandisk, but nothing like what was implied earlier.

Ricci has done some buffer tests with different cards and raw settings
