I'd be buying Delkin Power to save a lot of $ and pretty much match Cobalt performance. AFAIK, the larger capacity Delkin Power cards have been updated to perform like the 128 does in this graph and not like the 256 which sucked.
I bought 2 of those Delkin 128gb power cards, they were not at the speed TheSSDReview stated. I have a new PC with a Samsung 1TB EVO 970 Plus that reads/writes at 3,500/3,300MB/S and a 3.1 and 3.2 gen type C ports (10GB/S) and with both the most I could write a 90GB folder to the cards was 460MB/S on the front header and the back header was 645MB/s. There wasn't even a burst speed at that number. My Sony G 64gb XQD cards burst at like 1.3gb and after 3 or 4 seconds level of at 465MB/s. So i sent the power cards back and got the ProGrade 325gb Cobalt card. Also, I bought the Delkin Type B card reader as well.
Not sure how TheSSDReview got the stores they got. Those cards were dated 7/21 and 9/21 so these were newly manufactured as well. If anyone else tries them out, I would maybe go Amazon for ease of returns as they also have already set the return dates to Jan 31st (Holiday shopping return dates) as the earliest we will get the Camera 2nd to 3rd week in December.
The Prograde card reader came yesterday and the card will come today and will test the Cobalt card today just to make sure it's not my system, but I know for certain it is not my system.
Good to know. Let us know how the Cobalt compare when you test them with your system. If Amazon has a Xmas return policy now I will order some Power cards and test in the Z9. Power cards are still readily available from Amazon Canada. I'll check if Cobalt are also. I've hesitated buying any cards as I don't know when the Z9 will show up and normally returns are 30days which is still short of even the best B&H shipping date of Dec 15th. (I don't put much faith in earlier dates being thrown around on the internet as B&H is always correct with shipping dates).
With all the testing that went on when the R5 came out and people needed fast cards for 8K and 4K120, the Delkin Power were one of the better ones that had no limits on 8K. However, I believe Canon only required 400MB/s sustained to get 8K without hiccups.
Yeah I'm curious if the power cards work in the camera at that speed? But i should still get that speed writing to the card from my PC with bottlenecks or choke points. I might try them again once i get the camera. I'm 1st on the list at the store i pre-ordered from so I'm going to get it by the 16th or 17th
