Best Value For Fast CFexpress Cards 2022 | Field Tested on Nikon Z9 Canon R5 Canon R3

Great video! Thank you so much for the effort put into testing these cards. I am waiting for my Z9 to be shipped and will go with the Prograde 650 (slot 1, stills) and anglebird 2tb (slot 2, video)

Your welcome, I hope it helped. That’s a great choice Ed. I’d sure appreciate you using my B7H affiliate link if you’re ordering your cards through them. Thanks again for watching.

Thank you for your tests and these infos ,in Belgium,it is very difficult to buy this Z 9 ! here there is lists to buy one and 3/4 months delayed time !

[@Coolwildlife1]

Sounds very familiar, the UK is experiencing the same delays from what I read.

Wow....that was the best review...thanks

These CFexpress Type B cards are so incredibly expensive that SD UHS-II are more expensive. Biggest problem in figuring out the value of cards is how many times memory cells can be rewritten (cf. TBW) Then the question is if the card has a protection of data integrity (cf. spontaneous bit-flips). Third is to the temperature range they're guaranteed to reliably work in. Fourth, does card vendor provide a tool to inspect remaining card life (and, does it work as promised). Fifth, the best, fastest card of the moment is faster than the Z 9's buffer and so the camera never pauses to flush the buffer.

[@Coolwildlife1]

Solid points although with your fifth point when shooting in lossless compressed I have found that the buffer will be reached and slow shooting even with the fastest card on the market today. What card are you shooting in lossless that does not pause to flush the buffer?

Very informative, thank you, do you know if Photoshop is now able to process correctly Z9 Hi Eff files? Regards, John

[@Coolwildlife1]

Thanks John, I hope it helps you out if you ever need to buy a CFexpress card. Yes PS can open the hi eff * format.

@@Coolwildlife1 Once again many thanks, I really enjoyed your CF Express Card review.

This is great information. Thank you so much sir

Will any cfexpress card reader read the angle bird cfexpress cards?

[@jdelarosa89]

I just watched till the end and you answered my question. I purchased a 512 anglebird se card. The minimum write speed is 500mp/s I think. But I mostly shoot stills. Hopefully they work well!

[@Coolwildlife1]

Yes however to perform a firmware update on an Angelbird card you must have the Angelbird reader

What's up with the glow? It hurts my eyes.

[@jamesleahy3048]

Hello, I am considering buying some Angelbird cards today for my Z9 but the results from this test do not seem believable. The AV PRO SX has a minimum sustained write of 1480MB/s and the Z9 has a max output of 1200MB/s when shooting 20fps RAW. So the buffer should be limitless as the camera would never saturate this CFexpress cards write speed. My theory is also validated by Memory Card Speed Test channel here kzbin.info/www/bejne/f2jNmWmbbLGngM0 So, Im not sure what is going on in your test but the results do not match what others are getting on this card.

[@jamesleahy3048]

Even the AV PRO CFEXPRESS MK2 series have a minimum sustained write speed of 1300MB/s so the Z9 should theoretically also have a limitless buffer when using them. Care to offer a reason why this was not the case in your testing?

[@Coolwildlife1]

@@jamesleahy3048 I watched the video you are referring to and did not hear from the author whether he was shooting in lossless compressed, High Efficiency *, or High efficiency. That would alter the results greatly. Other testers performing tests on cards in the 1400 MB/s range like the Prograde 325 Cobalt also got around 80 shots before the guffer maxed out. The only other variable that did not appear to be controlled for was the shutter speed. If this tester had a shutter speed lower than 1/500th then he was not shooting at 20 FPS. The good news is you can buy Angelbird cards and be confident that they can handle the capacity required for the Nikon Z9's buffer.

[@jamesleahy3048]

@@Coolwildlife1 Ok, thanks for checking. So in your test, how can the Z9's buffer be getting hit if these cards 'claim' to have a minimum sustained write speed above 1200 MB/s? I'm really getting confused by this as I am sure a lot of others are too. I asked Angelbird, but haven't had a reply as yet. I would be grateful to hear your opinion on this as you have done exhaustive testing with this camera and cards.

[@Coolwildlife1]

@@jamesleahy3048 It's all math, but I do see where the confusion comes from. In lossless compressed the files are 66MB (approx) compared to 33MB in Hi eff * and 20MB in Hi eff. So at 20 fps you will be able to get a lot more shots until the buffer fills with the lower MB files. But looking at Lossless files at 20fps and 66MB per file in lossless that's 1320 MB/s pushing out to the card per second. If a card like the 160SX can handle 1480 MB/s or the Prograde 325 Cobalt at 1400 MB/s min sustained write speed you would think in theory that it would be a limitless buffer but it's not in my testing and that of others who have performed these tests. I can only think of two reasons why this would occur, either the cards are not sustaining the write speed advertised or the Z9 is pushing more data than the 1400 MB/s.
