Purchase was great, have to admit the labeling of the product was somewhat lacking. My original 325 cards were marked Cobalt, this new one wasn’t. A small thing to be sure, but you should be proud of your brand!

It’s too soon for me to review these cards. They were not dead out of the box, which is a good thing! Time will tell about the longevity of the product. Sorry can’t recommend these yet. Web site was great however.

This is a pro level card! Works amazing with Nikon Z8! Best for 4k and 8k! Blazing fast! Different league. One thing to note, little uncomfortable with the cards getting hot, but i am sure its taken into account!

Overall, this is a terrific memory and it is plenty fast for demanding high-speed photography and video. It will - as advised - get pretty hot to the touch, but this seems to be within the specification and I’ve seen no problems with this. So far, no data flaws or read/write issues at all, so my experience has been great.
LOVELY CARD, AND SUPER FAST AND RELIABLE.FOR THOSE LIKE ME, WITH A SOMEWHAT OLDER LAPTOP (3yrs), BE INFORMED THAT INITIALLY YOUR LAPTOP USB-C OR THUNDERBOLT PORTS, MIGHT NOT RECOGNIZE/READ THE CARD ACCOMPANIED BY THE CFx-CARD READER. UPDATE THE DRIVERS, AND REBOOT WHILST HOLDING IN THE SHIFT-KEY = PROBLEM SOLVED.ON MY NEW CANON-R3, THE CARD EASILY TAKES 200 RAW PICS IN BURST MODE AT 30 FPS.GREAT CARD, HIGHLY RECOMMENDED.
With the recent introduction of the Nikon Z9, I needed some cards that would write the data that the camera was generating without hesitation. With large RAW files flowing at 20 frames per second, it was important that the card keep up with the flow of images being generated. These ProGrade Cobalts do just that. And just as important, they read quickly when it’s time to ingest the files for editing. Again, the Cobalts come through beautifully. A perfect match for the Z9!
Recently purchased new CANON-R3. Started off using SanDisk 128 GB Cf Express Type B card. Camera would freeze/lock up when shooting extended bursts at 30 fps. Never had a similar issue on R5. Read online that the smaller 128 GB SanDisk card has much slower write speeds than published. Suspected this might be the problem. Purchase the Prograde card - - solved theproblem , no issues now what so ever on R3. Would highly recommend the Cobalt card for newer R3 or Z9 ( and avoid slower 128GB SanDisk card)
I decided to purchase directly from ProGrade and the process was simple. They shipped the product to me in a very timely manner and I’m very happy with the experience. I can’t actually review the performance of the product though, because I still haven’t received the camera I ordered last October. I did base my decision on Nikon using these cards for the majority of the testing I researched.
The Nikon Z6 II rejected the card. It took a roundabout way of formatting on the Mac, using ProGrade Refresh, then formatting in the camera to get it to work. Testing a few shots so far to see how it performs. No problem with the smaller memory sizes at all previously, so I hope this one works as well.
Reliable, fast and meets specifications. Excellent card with a Nikon Z9 or Nikon D850 (updated firmware). Meets specs and expectations. Bought more, and all great. Good metal wrapper.
