I have never had a Delkin Black get hot in my Z8. Warm, maybe, but not hot. Where it does get hot is in my Delkin card reader when I am offloading to my MacBook. I could keep my coffee warm then.
Best CFexpress card brands/models?

I bought a couple of Prograde Gold CFe 512 gb 4.0 cards. They work well in my Z9 and Z8. I am happy with them. But they are not faster than my 2.0 Delkin Black and Prograde Cobalt cards in camera. Roughly equivalent in my limited, non-scientific tests (discussed in another thread). Not sure about temperature — I have had no issues so far in either the Z9 or Z8.
Could in camera write speed change with a firmware update? I don’t know.
Why did I buy them? The price and capacity was attractive. They work well now in my Z9/Z8; they may be faster to upload on my computer with a 4.0 reader; and maybe, at some point, I will have a camera that takes advantage of 4.0 write speeds (would be great if that were a Z9 or Z8 with a firmware update).
My other cards are all 2.0 Delkin Black (128 and 325 gb) and Prograde Cobalt (325 gb). Happy with them too.

I will probably spend the difference since it is only $25.00. And I am assuming that I will not have any heat issues regardless of which card I select since I am not shooting bursts or video.

yes, in the z6/z6ii, although they can get hot in the reader
ProGrade CFe Type B are on sale right now.....the 256 gb Gold are only $128............... In the past I had to pay $1/gb.....

No, the PCIe 3.0 4 Lane has a limit of 1.8GB/s and that's a hardware limitation. Nothing a firmware update can do for that.
