ANGELBIRD’S STABLE STREAM™
SUSTAINED WRITE PERFORMANCE
Demanding formats such as 8K+ RAW recording or continuous shot photography place a heavy data burden for most camera systems.
Capturing detailed, high-definition frames requires a sustained write speed that does not throttle or drop off in performance as the capacity of the card gets used.
Angelbird Stable Streamâ„¢ technology supports the powerful sustained write speeds ensuring that a steady speed range is maintained throughout the duration of each shooting session for the entire capacity of the card.

FIRMWARE UPDATES VIA ANGELBIRD CFEXPRESS B CARD READER
To maintain optimal camera compatibility, performance, and full feature set of the Angelbird AV PRO CFexpress Type B cards, use the Firmware Update Tool accesssible exclusively via an Angelbird CFexpress B Card Reader.
While the AV PRO CFexpress B cards are compatible with other card readers available on the market, the ability to perform firmware updates is limited to the communication synergy between Angelbird cards and Angelbird readers.

If you really fill a 1 TB card, that means you also need at least 3 TB of storage for those files and at least two backups. We might sooner or later need storage solutions with hundreds of Terabytes. Even the files of my Insta360 camera are about 1 GB per minute. That forces me to delete the original files once I have converted them.
I'm now looking at having the R5 record video instead of stills and a 128G is looking mighty small. This is mainly due to Canon limiting the ways you can configure the shutter button in movie mode. For capturing it only supports "start+stop recording", while I'd like the following options:
1) Record only when it's fully pressed, the IR trigger will hold it down for the duration of motion, plus 5 seconds
2) Only start recording when pressing the shutter, don't stop. If the trigger sees movement, it will start the recording, but if it detects another movement while the camera is still recording, it will actually stop the recording.
Unlimited recording times would also get around that, but then I'd need an automated process to remove the non-interesting bits from the 10 hours of footage each night :) I've very, very jealous of the Nikon Z 9 'autocapture' mode they added in the most recent firmware. With that and a big USB-C power bank I wouldn't even need the triggers!
An example from last week, the R5 had trouble focussing, so I could stack 4 frames to get slightly more DoF :)
BTW when I travel for photography I often have several hundreds of GB of RAW (last 2 trips very close to 1TB each), and I know people saying they prefer smaller cards so they loose less if the card has a problem, I prefer a very big card to not have to change it every time and not having to worry about the free space ; I may be lucky I never had a card issue (I make a copy on computer in case sh*t happens )
Angerlbird makes a great card, but their firmware updates and potential compatibility issues with some cameras is sort of strange, seeing that the likes of SanDisk, ProGrade, Lexar, Delkin, and other top manufactures don't have this issue.
on the card are the maximum the cards can do. But sustained writes (e.g. video, holding down the shutter a long time at 20/30/40fps) are way below that. With the new SE cards this article talks about, the 512GB drops down to 800Mbyte/s quickly, the 1TB keeps going at 1300+ Mbyte/s.
@[email protected] will know the exact numbers, but I think the R5 itself tops out at 400-ish Mbyte/s, regardless of card.
The Z9's 8.3K/60 raw requires about 750MB/s write speed. Still well within the faster CFe Type B card capabilities.
Can't see a lot of long form video at 60fps though.
If the cards are using a non-standard way for firmware updates, we're out of luck and need to shell out the €110 for the reader or send the card to Angelbird for flashing.
