SANDISK 128GB Extreme PRO CFexpress Card Type B - SDCFE-128G-GN4NN

Works as advertised! Happy with the speed and quality! Would buy it again!

i have been using this for the last 4 years now, and it has been working great. lightning fast. didnt miss any moment. i paired it with the SD card for overflow for my nikon z7ii. so far, both have served me well. when we go on vacay, i do transfer them daily as im afraid it might fill up and ill end up not being able to continue taking pictures. now, i am looking at buying the 512gb. i also have another one of this for my d850 which i also put in an SD card for overflow.

I have consistently purchased SanDisk memory cards for my digital cameras. As a photographer engaged in high-end photography, it is essential to have the appropriate speed for recording images and videos. These memory cards consistently deliver reliable performance, and I have never experienced a failure with any of them.

This is lightning fast. Like, lightning lightning fast. I bought it for my Hasselblad X2D since transferring from the 1TB storage on the Hassie to my computer, with a USB-C, takes forever. At most maybe 45 megabytes per second. RAW files are like 230'ish MBs and with a few hundred you're suddenly looking at like 10+ GBs easy. But this SanDisk? Swept through 19.4 GBs in maybe less than 20 seconds. Just insane. And with 512 GBs, it has a ton of storage for my needs. I shoot mainly portraits and this bad boy will last me plenty of sessions. Still, this speed is otherworldly. I have a vid showing it transferring files from my Hassie. I just wish I bought this sooner.

Super fast and super reliable CFexpress Card Type B that I use in my Nikon Z6 model III camera bodies. I really appreciate the read/write speeds and the reliability of files (data) being stored on this card. I have a tendancy to use SanDisk after many years of high reliability; never had a bad experience with SanDisk (though I have had unreliable cards from other brands).

I never tried the XQD cards when they came out, primarily because they were more expensive than SDXC and their write speed was only slightly faster than the write speeds of the fastest SDXC cards (300 Mb/second). I do not shoot 4K video, which is what these cards were mainly designed for, but I shoot a lot of macro work with a Nikon D850, and most of that involves focus stacking - combining many images with slightly different focus points into one image with incredible depth-of-field. With the SDXC cards that "only" write at 300 Mb/second, my buffer would fill up after about 20 shots and then I would either be waiting for the buffer to clear, or shooting much more slowly. Having to pause and wait for the buffer to catch up made it more likely that wind would ruin the set or the light would change. When I saw these CFexpress cards advertising write speeds of 1200 Mb/second, I became interested. I installed the firmware update required to allow the D850 to recognize CFexpress, and then I tried one of these cards. To my delight, the camera buffer *never* fills up. I can literally keep shooting until the card is full or the battery runs down. Now I'm able to shoot sets of 100+ images. The only downside I know of is that these cards get very hot when shooting continuously, and when copying images to a computer. And I do mean hot, not warm. After ejecting the card, I hold it by the edges and wave it around to cool it faster. Time will tell whether these cards will stand up to many such shooting cycles, or if they will wear out sooner due to the heat generated. For the time being, at least, these cards enable me to do the type of photography that I love most. And, if I find a card reader that comes with a built-in fan or heat sink, I'll be interested in that.

If you need one of these, well you pay for it. I have been happy with SanDisk products.

I am a hobbyist photographer and they work as expected on my Nikon cameras. Much cheaper than Sony brand, and fairly often go on sale. I have about 6 of them and never had one fail.

Very fast and perfectly working

Used daily and never let me down. I have at least a dozen of these that I use on a daily basis in various camera bodies, I prefer to use small capacity cards rather than 1 large and am always inserting and removing from my cameras. I hate to think how many times these have been filled to capacity, files removed and then formatted with them showing no signs of letting me down.

Arrived ahead of the scheduled date. Well packaged in bubble wrap and sturdy box.

Works great
