Sony - TOUGH G Series - 256GB CFexpress Memory Card

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 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.

Fastest card I can find on the market. Keeps up with all of my photography and video.

Works just as expected. Plenty of storage good speed.

Super rapida, las recomiendo, garantizado.super confiable

These Sony cards are great, reliable and sturdy, they are all I use in CF and SD, although they are pricey, they are the most critical component of photo/video.
