ProGrade Digital 325GB CFexpress Type B Memory Card (Cobalt)

CF-Express is still relatively new and also relatively unused memory card so it's still VERY expensive memory, so you have to decide if you want the really fast write speed in camera, and really fast read speed when you want to copy it to the PC to edit the photos. Or use the cheaper not CF-Express memory. I decided to go for the speed for sports / wildlife photos, and despite it not officially being designed for the Nikon D850 (you may need to update the firmware if a D850) the memory is amazingly fast even in burst mode, and when copying to the PC the copy is also very fast, but you'll need a new CF-Express card reader to benefit from the speed. The only thing to note is due to its speed, this card gets really quite hot and quite quickly when copying files to the PC. Overall, I don't think you'll regret this card.

The best card for canon r5

Expensive but well made and more importantly fast write speeds

Superb card with outstanding write speed. Will buy again

After spending hours researching these cards for my new Canon R5, this came out on top as the best for speed, reliability and value for money. Compared to the other options, this is definitely the best pick. It’s faster than everything else at the price point. The reason for the drop in one star has nothing against this item in particular, but the fact that these new CF cards are wildly expensive. I hope that the prices decrease in due course as they become too popular. I wouldn’t advise using these unless you’re pro, just go for a fast SD card instead if not and save the extra cash for a new lense. A quicker card is not going to help you take better pictures after all, but if you’re pro, shooting on two cards is essential.

These work great in my Canon R5.

Fast, reliable, cool running, high quality memory card. Works well, clears the buffer extremely quickly and very quick to download images too. Just a little pricey but hopefully the price will start to come down.

This is the second of these cards I have purchased. Not the cheapest but certainly cope with the speed of read/write required by my Nikon Z9

Fast and furious. Great value for money. I use it in my R5 and its blazing fast. The only con is that it heats up a lot in camera and also in the reader.

Hervorragende, schnelle Speicherkarte mit absoluter Zuverlässigkeit in meinen Canon Kameras. Sehr empfehlenswert, allerdings nicht billig

ProGrade Digital have been fantastic to use over the years and highly recommend. Super fast and reliable too.

This memory card arrived very promptly after ordering in perfect condition in commercial packaging. I decided to spring for this CFexpress Type B card after reading of what an improvement it is over the Sony XQD G-Series card I had been using originally. And they are. The CFexpress card capacity is 165GBs and writes at 1500MB/second. The old XQD G-Series cards cost the same but were 120GBs writing at 400MB/second. That is a big difference. Especially when using video recording. But I needed to buy a new Unitek card reader ($50CAD) for larger file transfers. It should be noted that I paid $247CAD in May 2023 for the CFexpress card and now in November 2023, they cost $177 for the same item. I bought too soon but it is good to see the prices dropping for these new cards that are becoming standard for our digital cameras.

Super performances mais à bien plus d'1€/Go, c'est vraiment très cher par rapport à la concurrence. Emballage minimaliste, fourni sans boîte de protection en plastique. Cartes utilisées sur un Canon R1. Elles encaissent les 40im/sec sans soucis.
