p.1 #1 · R5 - CFexpress 4.0 Type B or UHS-ll SDXC?
I am experiencing the known over heating issue with the Sandisk CFexpress cards. It's quite concerning how warm they get actually. I didn't know about the issue until I bought and used a couple of them and searched the interwebs for answers. I have since bought a ProDigital CFexpress card and it has worked flawlessly so I am considering adding a couple more since they are kinda on sale during the B&H BILD Expo.
I do have several of the Sandisk UHS-ll SDXC cards. Even though they do not overheat, it seems they can't keep up very well when sprayin' 'n' prayin' a fast moving subject. It is my understanding that the CFexpress are best suited for video capture. I don't shoot video, but I can see where shooting fast sports type action might benefit from the 'faster-then-SDXC-card' read/write times. Am I understanding that correctly?
I guess my question is....if you were replacing cards that are known to malfunction, would you choose CFexpress 4 Type B or UHS-ll SDXC?

I’ve found that SDXC cards can slow up my R5 considerably when shooting a still sequence, so I’d go for CFExpress - and my ProDigital CFExpress cards also work perfectly

I have an R5ii which, from what I understand, may have a higher data throughput than the R5. That said, I have had good luck with OWC CFExpress Type B cards. They're reasonably priced (for CFE cards) and stellar performers.

CFE-B is so much faster than SD that it's not worth using SD for backup if it's going to get in the way of a functional buffer during burst shooting. Dumping photos from them to the computer later is always way faster. There is no maybe or "might benefit" here...CFE is simply faster and better for all use cases.
I'm never buying another SD in my life if I can help it.

Buy some Delkins Black CFe cards. They run noticeably cooler than the SanDisk cards in the R5 IME. Although some CFe card models run warmer than others, it is possible to overheat the camera with any CFe cards after enough continuous use.
Neither the R5 nor R5 II take advantage of the CFe 4.0* card speed compared to CFe 2.0, but they are faster in some readers and more likely to be useful in future cameras.
*Note that there was no CFe 3.0 specification. The CF org went directly from 2.0 to 4.0 to align the number with the PCIe version. CFe 2.0 uses PCIe 3.x and CFe 4.0 uses PCIe 4.x.
Amazon had Delkin Devices Black CFexpress™ Type B 4.0 512GB for $230 but they must have sold out. They still have that card in 1TB for $400.
" . . . ensuring sustained write speeds of 2040MB/s for reliable, high-quality recording with zero dropped frames . . . Engineered to withstand extreme conditions, this CF express Type B is shockproof, waterproof, and resistant to temperature extremes, safeguarding your valuable data in any environment . . . "

I would recommend going with either Nexstorage Type B1Pro or Delkin Black type B cards. For v90 cards I use ScanDisk Extreme Pro or Nexstorage cards. Never had any over heating issues with these cards with the R1/R3 or R5ii.

It depends on the definition of overheat, i.e., do the bars progress at least halfway or does it literally shut down? I consider overheating to be when the grip becomes quite warm and there are 5-6 bars. At that point I switch to another body and let the first cool down. If you do not do high-res videos or shoot over 5,000 frames every hour it may not apply. Regardless of the criteria, cards that use less power keep the camera cooler and yield more images per battery.

Thanks for all the responses.
One thing though....I am seeing that the CFe cards are actually less expensive than the SDXC cards of equal capacity. Seems like a no-brainer....right up my alley!!
Here is a thread I found here on FM discussing the heat issue if you'd care to have a look. On an additional note, I noticed that the Sandisk cards would get very warm...almost hot...if I left them in the card reader for very long after transferring the files to the computer.

In camera heat isn’t a concern if you just buy Delkin Black to begin with, but I’ve had card readers that got them way hotter than burst shooting ever did.

I'm just going to re-plug OWC CFE B cards. I own two 1TB cards. Yes the R5ii doesn't support 4.0 but the OWC CFE B card reader does. And I'm constantly amazed at how fast it transfers huge files from the card to my PC (which also supports 4.0 speed). And my 1TB card normally is $300, but goes on sale for $250.

OWC is clueless about customer service and had a major debacle with the Type A cards a few months ago. They had cards with bad FW and you needed to use a $100 OWC branded Type B reader with a Type B to Type A adapter to update the FW. Some Type A cards were shipped with the adapter and some were not, with little rhyme or reason. They did not even have the corrected FW freely available on the site for a long time or any service advisory on the site indicating the cards had a problem.

Interesting thread
if I understand it correctly if you are shooting a lot of continuous frames any type of SD card available may struggle to keep up
In that situation better to use the CF express card only
I use a Delkin black CF express with either a Trancend v90 or Lexar v60 SD card
I shoot wildlife and at the moment macro multiple frame focus stacking and only rarely get an issue with buffering but do get that some people need to shoot a lot of continuous frames
I like the peace of mind of having the backup SD card

The Prograde cards are the best bang for the buck with the 512 GB two pack generally the best buy. These are generally faster than other alternatives and if you are shooting in high volume situations better than the SD cards. I have used them with success on the R5 and R5 II. I have never had any issues with them though they do produce some heat that I notice more in the uploading them in the card reader.

EB-1 said : "Neither the R5 nor R5 II take advantage of the CFe 4.0* card speed compared to CFe 2.0, but they are faster in some readers and more likely to be useful in future cameras"

Sure, but in many cases the newer CFe 4.0 cards are cheaper than the older CFe 2.0 cards they replaced. The SSD industry has moved from PCIe 3.x to 4.x and now 5.x is the thing.

The shorter version - dual CFe is a big "wishlist" item for most experienced wildlife and action shooters for a reason. I don't think anyone has ever jumped for joy when a body was dual SD.
Also, it's true no R body can take advantage of CFe 4.0 speed, but many manufacturers have already stopped making CFe 2.0. So just buy the most reliable brand at the least cost per GB. Don't even consider generation at this point.

I was pretty glad that the Nikon 7000 series had dual slots. Then they screwed it up when the D500 came out by removing features from the D7500 like the 2nd slot. There was no CFe in the D7000/D7100/D7200 era. The equivalent Canon bodies of that time had only one slot, period. They did not get two slots of any kind in the croppers until the R7. I suppose some would prefer one CFe (I would) rather than two SDxC. The combo Type A/SDxC slots like Sony are ideal in the medium res bodies if you need two slots.
