Looking for another CF Express card for my R5 and this is my first camera that has used them so haven't developed a favorite so far. Was generally using San Disk Extreme Pro SD cards and never had a problem with them but both some Lexar SD XC II for my R and was using them in my R5 and it kept crashing because they were too slow--probably my error. Don't want to make that mistake again. I currently have a SanDisk ExtremePro CF Express for my R5 and it seems to work great. Don't know whether to just stick with that or it folks have found something they think is more reliable/durable. Thanks--

If you want to try other cards I would recommend Sony Tough G series or the Prograde Cobalt series. Both should work great in the R5. I use Sony Tough G cards because they have solid read speeds and are made exceptionally well. The Tough G SD cards are especially robust when compared to normal cards.

You only need the ProGrade Cobalt if you are shooting high resolution video. I use the regular ProGrade cards. Have only had the 1Dx III for a month and can't shoot any sports now, so hard to know if any problems, but I've used ProGrade CFast and ProGrade SD ever since they came out and never had a problem. I've had a lot of problems lately with Lexar SD cards, so I'm no longer buying Lexar. ProGrade has the advantage that they are cheaper too. I buy 128gb cards because I'm shooting stills and that's way more memory than I need for stills. With CFExpress, I believe only SanDisk makes 64gb cards. 128 seems like the minimum you can get in other brands.

Yeah, I'll keep those Lexar SD Cards for my R--speed certainly isn't an issue there :LOL: and just go with CFExpress in the R5. Thanks for your input

I'd get a card that has been tested with the R5. All the cards overheat, I don't know if better tech is coming or not. I've only seen one where the manufacturer specifically says it was tested with a R5, thats the Delkin. They also detail the overheat and how the card slows down to counter it as much as possible. I expect they all have some sort of feature to do that, but don't tell you.

I expect any of the high end cards will work, but I haven't seen technical comparisons.

I have a Sony Tough UHS-II card that started corrupting files a couple months after the warranty ran out. It was not part of the recent Sony recall. It was my only Sony card. Now I'm trying ProGrade Cobalt.

Had another Lexar SD Card go bad yesterday. This time the read/write switch fell off (have no idea where or when) and card now thinks it is read only. That's the fourth Lexar SD Card I've had go bad in less than a year. All were purchased from either B&H or Adorama, so I'm sure they were genuine. The quality control just doesn't seem to be there anymore.
