p.1 #6 · 5D4 - What Speed/Type of Memory Cards Should I Buy?
I bought Lexar Pro 64 GB 1066X CF cards and SanDisk 32 GB Extreme Pro SD cards (raw on CF. jpegs on SD). I don't do video and for still photography this is plenty even for long assignments.

If you want to be recording 4K movies, I would strongly suggest you get a 256GB card. Using that card will force the camera to format the card in exFAT, thus allowing for files bigger than 4GB (or, more importantly, longer than 1 minute). Otherwise, you will either get movies in 1 minute increments which is a pain, or you will have to format the card in exFAT using your computer every single time, which is a pain as well.
256GB SD cards are much cheaper and do work - most of the time. I have Lexar a 256GB SD card that usually works but sometimes recording stops after a couple of seconds. It always works when using a 256GB CF card, but obviously those are much more expensive (I have a Lexar one).
Why the camera doesn't always use exFAT, or at least give you a choice, is beyond me. The 1DX2 always uses exFAT on the CFast slot, which is at least something.

Yes I have those exact cards Geoff described, 128GB for each type. If you do 4K video you need a card that can do at least 65MB/s writes, note that is megabytes not megabits. The San Disk has been benched as the best performing UHS-1 card, although why the hell they didn't go with UHS-II is baffliong.

The cameramemoryspeed site is great. Sometimes sites with names like that are basically just spam but that has actual data.
I wish I'd checked it out more thoroughly before purchasing SD cards for my 5D4. I bought 128 GB cards from Lexar that are labelled "95 MB/s" but that's only the read speed (which is mostly meaningless for a digital camera!) and they are not fast enough for 4K video. Even if you think you're never going to use the 5D4's video capability, it seems like a good idea to get cards with faster write speed. I returned the cards and instead bought the Sandisk card that's listed on the page.
Zach, my personal opinion on card size is that you should have a big enough card so it's never a hassle to switch - enough space so that you're not forced to switch mid-action - but not so large that you can put a whole day's shoot on a single card. Also, I think using the 5D4's dual card option is essential. I also got fast CF cards for my camera too and for anything important, the camera is writing to both cards simultaneously.

If you are writing raws to both cards at the same time then the SD card is slowing things down (unless you have a slow CF card). One way to speed it up is to write only to the CF card, but then you are balancing card redundancy against reduced buffer clearance time. Which has been costing you the most images ? Which *might* cost you the most images ?
An alternative might be to write JPGs to the SD and raw to the CF, but then you might incur some processing delays depending on camera settings and lighting conditions. e.g. for noise reduction, lens correction, etc.

Hello,
IŽam sorry to insist on this topic but can I use a card like this to shoot 4K video like with a CF card?
SanDisk Extreme Pro UHS-I SDXC U3 95MB/s 256GB
Its a question of price vs performance or best value. SD are less expensive than CF. Are they good enough oo for the job?
Also, with this capacity I will be able to use ExFat format in camera and record 1 file instead of several smaller files.
My doubt is if I can do the same with a 128GB card or just 256GB?
Will this be really important when editing? Or its not a really big issue?
