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.

fwiw, the blacks work a bit better than the cobalts after hitting the buffer. they stutter less.
Sony makes a reader that reads both XQD and CFexpress B
Sony model # MRW-G1
The Sony XQD reader won't read CFexpress B cards.

I could not find a combo XQD and CFepress reader that customers were happy with in actual use. I already had two XQD readers and so decided to add two CFexpress readers. I chose readers from two different companies so if I have a problem with file transfers I can rule out the reader as the problem. Two readers also provide a backup reader for traveling.

i use the sony that @Irap mentioned without issues, but i think in general trying to find a single reader for both types of cards tends not to be an overly useful optimization. i found that as i started to use cfe-b cards in a camera that could actually push cfe-b, that i more or less stopped using the xqd cards.
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.

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

There is this option - 165 Gb Prograde, also high write speeds at relatively low temperatures. My take is this is standard test bench, which serves to compare cards with some confidence. There's sufficient experience to take the known best performers as benchmarks for comparing cards using this site's data eg Delkin Black

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.

Going to video I wanted to use internal CFexpress cards so I could shoot 8k at 60 fps. I found the Delkin 2TB CFexpress cards on sale for $450 at B&H and bought two. Testing with video and with stills at 20 fps I had not problems with these cards.

The latest CFexpress 4.0 Type B cards: 512GB, 1TB, and 2TB. VPG is the allied standard that certifies minimum write speed, but these Prograde far exceed VPG 4

Just returned back to the UK from my US trip in Illinois and Florida with a 1.3 TB ProGrade Cobalt on my Z9--not a lot of folks here mention this new model. Absolutely amazing stuff--also bought a ProGrade branded USB 4.0 enclosure for that. Great stuff, never held back on very long 20fps photo sequences, and any format videos are no problem, obviously.
Great prices and specs on ProGrade‘s new cards!

i'm very curious to benchmark the v4 cards on my system since it doesn't support v4 and i'm curious what the effective performance is. but atm only large cards were available and i'm a bit hesitant to spend that much on a big card which probably won't have any benefit to me in the medium term

For stills, I don't need v4. It appears to be aimed at high quality video to avoid dropped frames

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.
i haven't seen a single camera that actually implements v4. i assume we'll see some new cameras soon that use it.
i'm curious about the video formats that push past what's capable with the current cards as we're seeing sustained bitrates of over 1600MB/s without going to v4.
