Cobalt in 325GB and 650GB which are ones that provide better performance with Z9 testing. Delkin Black is going to provide comparable performance. Others may be OK but the Cobalt and Delkin Black I know are going to work for burst mode or video.Prograde Colbalt or Gold?
The catch is this is only for the very large ProGrade Gold cards. The 128 GB card is 90% slower - painfully slow. This was also on a test bench rather than in a camera.Impressive performance - Prograde CFEXpress B 1Tb card tested

I have two 64GB that I used in the D850. Now I am using them as the Archive Card with the baseline menu settings for my Z cameras. They stay in the memory card wallet unless I mess up the settings on a camera and need to re-baseline.I sold my XQD cards and readers rather than dealing with two different formats. I think I originally paid $89 for the 64GB Lexar XQD card and sold it for $50. Prices have gone up now, but there are still plenty of people with D500 and D850 cameras that can use the XQD cards. It also worked well in my Z6 and Z7ii - really just a matter of selling the older product while it still had value. It was a good deal for the buyer and allowed me to move to a single format.
you can only (theoretically) sustain about 25fps lossless raw on the fastest cards (nikon z8/z9 estimate), so i think we will have stills applications for faster cards.For stills, I don't need v4. It appears to be aimed at high quality video to avoid dropped frames
