Designed for emerging mainstream imaging applications, the 256GB CFexpress 2.0 Type B Gold Memory Card from ProGrade Digital provides read speeds of up to 1700 MB/s, which helps to quickly offload content to your computer, and write speeds of up to 1400 MB/s.

ProGrade Digital 256GB CFexpress Type B Reviews
Good card at a good price
These cards don't overheat like a number of other well known brands and come at a reasonable price.
2 pack savings
I picked up a couple more 512s for my Canon C500M2, but I also use them in the R5. Since arriving a few back Pro Grade has been my brand of choice. They've been rock solid for me. Cheers.
Works great with my R5
Based on information, felt it should work great with my R5 as it does.
ProGrade CF express card 250GB
Hey, it does what it's supposed to do. I don't shoot video and it's write speed for even fast action photography is fast enough for me.
Love ProGrade CFexpress cards!
My ProGrade cards, 128, 256 and 512GB just keep on working, no problem at all and they are very fast!
Worked for awhile, then failed
I thought this was a pretty good card until it failed. I would not purchase again. I'd recommend spending hard earned dollars on a higher quality unit. Very disappointed.
The card processes images very quickly. Even when there are multiple images to process at the same time.
Perfect for Panasonic GH6
Using these on my GH6 cameras. Seem to be working great so far. Have had for about 4 months.
