I have been a loyal Sony Toughcard user and recently bought a Sony Tough CFexpress B card 512 GB ? When Itook this card out of my R5 camera today a piece of it fell off in my hand. Thecard has never been dropped and isn't that old. I am thinking with the highheat temperatures these cards are seeing with the R5 and even the card readerthe plastic is degraded. It almost looks like there are small cracks around thecard in different spots. My fear is over time the card will continue to fallapart and I am out $650. I called Sony today and they said they will notreplace it because its physical damage. I told them I think it's amanufacturing issue but they didn't want to hear it. They refused to replaceit.

I have been using this card in my Canon R5 and it has been very good for write speeds with no buffering that I have seen. Granted I don't take a whole lot of video or keep the shutter button pressed for long periods of time. When reading data off the card to my iPad Pro with a card reader and it is exceptionally fast getting off all the RAW images to Lightroom. It takes seconds now instead of minutes when I was using an SD card. Would highly recommend this card and have been using Sony Tough G Series for a long time with no issues.

I bought this to use in a Nikon D850 and it works well. However, it is cumbersome to use with Lightroom 6.14 on Mac (I bought the Lightroom software with the perpetual license). I bought the Sony CFexpress/XQD card reader to download the data from the CFexpress card. I suspect the problem is that Lightroom 6.14 wasn't designed to work with CFexpress cards. I imagine if one has a newer version of Lightroom, it would work fine. I believe the problem is with my old version of Lightroom and not the CFexpress card which otherwise works well in a Nikon D850.

Memory cards are about as exciting as trash cans. You need them, and it's nice to have a big one for the times that you need it. That's where the analogy ends, because these CFexpress cards sure are expensive, and it does help with the workflow if they are fast. I returned the 128 GB one I bought at first, preferring to spend the money now and not worry about card space or buying more cards for the foreseeable future. This thing just works, it's fast, it does get warm to the touch. With my ProGrade card reader it just shows up as an (internal?!) drive on my PC. No issues at all. My only qualm is the eye-watering price!
Solid, reliable, and great speeds. As impossible as this may sound, Sony currently makes the best of something and its CFE cards. You do pay a hefty premium for it, though, so this does not necessarily make Sony CFE the best choice for everyone.I use the Prograde USB3.1 gen 2 (10Gb/s) CFE-B/SD-UHSII combo reader, because my Nikon Z6II uses both of those formats and this is very convenient for my workflow. I highly recommend this brand of reader over all others, including the Sony reader(s). To get max transfer speeds, make sure your computer supports the fastest USB specs, and that your computer storage device is capable of reading/writing at least as fast.At the computer, all CFE cards are going to be fantastic. So, I won't even bother posting a bench result or ... MoreSolid, reliable, and great speeds. As impossible as this may sound, Sony currently makes the best of something and its CFE cards.

So, I won't even bother posting a bench result or saying much more. Provided your computer is fast enough, CFE transfer speeds are amazing and any difference between brands, size, etc., of the CFE card is largely irrelevant. It ridiculously fast. 'Nuff said.In the camera, well, your results may vary. In my Z6II, there is not much advantage over, say, an XQD (G) 120GB card. Is it a little faster, yes. Faster than the best SD UHSII cards, yes. Between difference brands, models, sizes, etc., CFE cards, yes, there can be a difference in performance. However, it won't be much if at all, and begs the question does it even matter. Unless you do burst photography all day every day, the difference from one CFE card to the next just won't matter. I will say that this Sony CFE 256GB card is noticeably faster than my Prograde Cobalt 325GB gen 1 card in burst photography buffer clearing. Meaning, the number of burst images I can get before the buffer is full and the camera slows down is greater on the Sony than the Prograde. And after the buffer is full, the Sony will keep the camera in a faster slow burst mode. That will not matter to everyone. If you are advanced/pro, this will not matter. If you are a novice wildlife photographer and your go to technique is spray and pray, this deeper effective buffer may matter to you.For video, I can only reference the Nikon Z6II 4k 144Mbps video. Of course CFE is fast enough for that, but so is any XQD card, UHSII cards, and even some UHSI cards. I think the only issues might be with HQ 4k/8K on a few, select cameras that have super high bitrates. You might want to look into the Prograde Cobalt cards for that, which tend to have a slower burst write but higher sustained write speed rating than the Sony Tough line.I got mine on sale and used rewards I had built up. Hard to pay such a high premium, but Sony makes a great CFE card. If you lean towards photography, pretty much any CFE card will do. If you lean towards video and your camera supports HQ high bitrate, might want to consider researching/investing in cards with a higher minimum sustained write speed such as the Prograde Cobalt cards. One final note. These are not SD cards, which in my experience have a high rate of failure and, therefore, a limited lifetime. CFE cards are built to last, and you should factor that into your selection of size/cost.
When Sony claims that their memory cards are TOUGH but will not warranty that Toughness it is a hollow claim. Especially when there is a defect in the plastic case. No way to repair and Sony says, Physical defects or damage, not caused by dropping, is not covered by the warranty. So I am out $600 with no option to fix the card. They say the card can be dropped 15 feet. Mine was not dropped and still parts are coming off the card. I can't risk putting the card in my camera and plastic getting stuck inside. So the card is useless now! Shame on you Sony for not taking care of your customers.
Prior to purchasing theSony Tough CFExpress card, I purchased a ProGrade 512 GB Gold 2.0 CFExpress card for use with my Canon R5. The very first timeI attempted to take a 4K HQ movie with my R5 and the ProGrade card, the camera stopped recording after a few seconds and stated that the card's write speed was too slow. I continued to have this problem intermittently with the ProGrade card. Sometimes the ProGrade card would work fine, and then only a few minutes later with the same setup, I would get the card write too slow message. I returned the ProGrade card and purchased this Sony Tough 512 GB card. I have recorded numerous clips now with the Sony Tough card with every resolution and frame rate ontThe Canon R5 and under a variety of conditions including hot outdoor ... MorePrior to purchasing theSony Tough CFExpress card, I purchased a ProGrade 512 GB Gold 2.0 CFExpress card for use with my Canon R5.

If you want the best CFEXPRESS card for your Nikon mirrorless camera, this is it. 256gb is the sweet spot. Read and write speeds are very impressive. I use this card and I have no regrets. Its reliable and these cards rarely go bad.
I have been using my first 256GB Sony CFexpress Tough card for well over a year with dozens of cycles of photos. It is one tough card and is fast fast fast! Writing speeds are perfect for video or burst photography and when you go to read from it, it downloads to your equipment with ease and lightning fast speeds.I just bought my second card as I like to have a backup of the CFexpress for travel photography. Not cheap but, like they say, You get what you pay for. Worth every penny of the investment.
These guys are well built and super fast. I use one in my Z6ii. I use the Sony CFexpress reader to transfer raw photos to my PC for editing. The transfer is practically instantaneous over USB-C. I sure do wish I could have taken advantage of one of the many sales I've seen on these cards since I paid full price for mine, but I'm satisfied with it. Either ways they're still quite a expensive.
