That doesn't sound good. Seems the old problem has reared its head again.
I've never hit the buffer in the field before. But I shoot CRAW.
Off topic: Yesterday I did a quick shoot to FPS stutter test at 12FPS in MS (not EFCS) in RAW with a 57MB files size and could only get about 100 shots on the Transcend. Today I should have the time to do the shooting till 30s test. I did note that the Transcend comes to a pretty abrupt halt and just does a few 1-3 shot stutters after it halts unless I let go of the shutter for a few seconds to give the buffer a chance. The card write light took about 7s to clear with those 100 shots.
I was shooting in CRAW. As a matter of fact I have not done a shoot in full RAW even once since I got the R5. The only time I shot in full RAW was the speed test I did just recently.

I did the 30s test with my 256GB Transcend CFExpress card.
I was only able to get 221 shots in 30s with 51.6MB files. That was EFCS/MS at 12FPS in RAW.
There were some more than a second long pauses with no shots being taken during the last 10s. The final 2s had no shots taken and there were a few other breaks like that.

So, good to see the consistency, but corroborates the Transcend cards as not the quickest. That said, they're all plenty quick, and the buffer is large. And the Transcend cards are reasonably priced.
I just performed some in camera card tests after running tests on my PC that concern me. The in camera tests seem to be inline with what others are posting here, however, speed tests from my PC seem off.
Card: SanDisk Extreme Pro 512 GB CFexpress B
Camera: Canon R5 with Canon battery fully charged
In camera test
30 sec, 49 MB files, Mech shutter, 12 FPS, RAW: 323 shots
PC tests:
USB C port, Card reader: SanDisk Extreme Pro with USB C cable that came with reader.
Write: 421 MB/sec, Read: 415 MB/sec
Ran the test a number of times and got similar results each time.
Shouldn't I be getting much higher values on the PC test?
My internal NVMe SSD is giving much lower speeds than it should be but I'm unsure if it would impact the card tests from the USB C port.
SSD is Samsung PM991 NVMe is only getting 166 MB/sec Write, 1106 MB/sec Read

Which Delkin? From what I've seen, the 64GB and 128GB Delkins have updated firmware that makes them among the best performing cards on the market...while the 256GB is still using older firmware at the moment that bottlenecks on sustained write performance.

It is more likely the case that you are either using a USB 3.1 / USB 3.2 Gen 1 port or cable. USB-3.1 or USB-3.2 Gen 1 are both limited to 5gbps, which translates to around 500 MB/s.
USB-C is a specification of a connector and required wiring. Much like USB-A (“the normal one”), USB-B (“the printer one”), Micro USB (“the old smartphone phone one”), and Mini USB (“the worst one”).
USB-3.1 and 3.2 are specifications of the protocol that runs over the cables. Your USB-C cable may not be compliant with USB-3.2 Gen 2.
Similarly your USB port on your computer may not be compliant with USB-3.2 Gen 2. You need a USB 3.2 Gen 2 cable and port to get the maximum speed.

Folks, there's a firmware update on the Angelbird card. And - a first - it's user-upgradeable, so long as you have Windows and an Angelbird card reader. I was able to successfully complete the upgrade this morning, and the startup delay is now completely gone (R5 firmware upgrades previously had limited the delay to once at the beginning, but that can still be annoying at times). It applies to the XT cards. More info here.
I will re-test the card for speed performance and republish the review of cards after.
I had a back-and-forth with the folks in Austria, and they indicated a Mac version will be out soon too....Show more →
Thanks for the update. Any other feedback after the new firmware? I'm looking for the best card(s) between 512gb and 4tb (Angelbird has one in the works). On a shoot the other day just doing very short 4k 120fps clips I ran through my Sony Tough 256gb card in an hour. I'm not sure how much total footage I took but I was surprised when it ran out of space as the clips were only ~5-20 seconds long each. 4k 120fps takes up A LOT of space.
I'm looking at the following cards based on your reviews and others online:
-Sony Tough 512gb
-Prograde Cobalt 650gb
-Angelbird 1tb
-Angelbird 2tb
-Angelbird 4tb
I wasn't considering Angelbird until I heard they fixed the boot up issue but they sound like a reliable brand with great speeds now that they got that sorted

Alpha, yes, we added that into the review stats. You can see the new comparison against the whole cohort here.
These cards have a fantastic reputation among video shooters. I haven't seen much in the way of stills comparisons, aside from what we've done here.
Personally, I'd recommend them over Sony, even though the Sony is slightly faster, based on price and Angelbird's service versus Sony's. Also, Angelbird is the first (and only?) manufacturer to come out with a user-executed firmware update.
Delkin is also a great option, similarly priced and with fantastic service.
Is the date and code you are referring for the Delkin 128gb card, to the left of the UPC code I just got one that says the following right above where it says “made in Taiwan”:
022121 01832594HM MB10
I’m assuming the first set of numbers is the date and the last 4 are MB10. Just want to make sure the first set is the date and the MB10 firmware is okay.

Mine says "HM" is that what you meant by "MH"? Also says 8/20 which I suppose is the manufacture date.

I ended up returning my Delkin card and just sticking with my Transcend card. So I can't recall exactly where the lettering or the 8/20 was written.
Thanks for letting me know! I’ll check with the individual who posted about the Delkin initially, as I don’t see the 4 digit month/yr code on my package.

Do you remember where the date codes were on your card

I’m assuming the first set of numbers is the date and the last 4 digits (MB10), are a batch or firmware number. I don’t want to open the package if it’s an older batch. I first thought that the first set of digits was the date, but that would put the production date as Feb 21, 2021, but that seems to recent to go from production to a store in Calgary.

BobbyTan, whoever you are buying from, tell them you want a Delkin 128GB card(s) with a date (mm/yy) on the back of the package newer than 09/20. That will get you cards with the new firmware that is 1gb/sec sustained write speed, as per thessdreview.com review.
I have about 200GB of CF cards that are fading into obsolescence as my 7DM2 transitions into backup status. I am of the opinion that the CFexpress format will be around for quite a while and will probably have some period of downward compatibility beyond that, so I made my purchase based on a combination of current needs, price, performance and 'future-proofing' (I know there is no such thing - maybe 'future-prolonging' is a better if not more awkward term).
khurram1, in a conversation with a Delkin tech rep, I was told that the earlier Delking rep was incorrect about the significance of the dates. He said the only thing that matters is the firmware code and that HM is the most recent firmware (at least, it was as of a few months ago). Based on what you posted, you have the most recent firmware.
BTW, I suggested to that tech rep that he make a post to this forum to eliminate the confusion around firmware versions, or in the alternative, I would be happy to post something on his behalf but I guess he wasn't interested in doing so.
