SanDisk 128GB Extreme PRO CFexpress Card Type B - SDCFE-128G-GN4NN, Silver

Very high record speeds - able to handle whatever recording used - up to 8k without issue. Dependable manufacturer that always produces high quality products. Have only used it a few times since purchased a few weeks ago but recording from a Canon R5 and later transfer from card to PC have been super fast and reliable. Capacities appear to be correctly identified and in camera formatting is quick and easy.

Good card; good price. Works perfectly in my 1dxiii

Fast, Excellent Storage for advanced Cameras.

I've generally used Sandisk for all my cards going back to 2010 with my Nikon D7000. I'm now using a Nikon D850 and this card works reliably. Honestly I'd rather have a reliable card than the fastest out there. I'm using this card with a Prograde Reader and it does get quite hot. I've heard this is normal but it still concerns me.

Great price on an excellent and extremely fast memory card! Allows my camera to work to its full potential!

These work well in my camera and Ilike the size.

Speed and stability are where this card shines. File transfers are lightning fast, and it handles high-bitrate 4K without a hiccup, making it perfect for professional video workflows. Build quality feels solid, and it performs consistently under pressure. The only drawback is the price. It’s definitely geared more toward serious creators than casual users. Still, if performance and reliability matter most, it’s a worthwhile investment.

I use a MAC Studio and have daisy chained two LaCie 2big Dock units. The first is an older unit which does not support the CFexpress card format; it has on its front a USB 3.1, Compact Flash and a SD card reader. It is used as a Time Machine for the Mac and has and continues to work perfectly. I recently purchased a new Nikon camera, which uses the CFexpress card and an updated LaCie 2big Dock unit and daisy chained it to the Time Machine. The updated 2big Dock has card readers on its front, same as its predecessor, and supports the newer USB 3.2, CFast 2.0, CFExpress and the SD card. Open System Settings by clicking the Apple logo in the upper left hand part of your screen, then click About this MAC and finally More Info... You will be taken to System Settings, General, About. Now click System Report at the bottom of the dialogue box, under Hardware, click Thunderbolt/USB4 and at the top of the resulting screen expand the TB tree by dragging on the bottom of the dialogue box to reveal Thunderbolt/USB4 Bus 3; note that the MAC OS see's the device as an SSD Hard drive and not a removable drive. This means that inserting the CFexpress card into the reader does nothing. The card is not recognized within Disk Utility or in Finder and therefore the user is unable to import images captured to the CFexpress card using the newly acquired LaCie. I have only explored one option thus far, which is to connect the camera, with the CFexpress card inserted, via USB C cable directly to the MAC Studio. The camera is recognized and an import of the images proceeds, ...slowly, I might add. I am not knowledgeable enough to determine exactly where the problem lies. Is it something within the LaCie firmware that causes the MAC OS to recognize the bus as an SSD or is the MAC OS configured to not recognize third party CFexpress readers. Who knows? I spoke to Apple today, the Best Buy Camera dude and they both concur and advise to connect the camera directly to the MAC. Will research 3rd party readers tomorrow and update as necessary. Anybody have any further experience with this pls share. I am trying to declutter my work area as much as possible and the last thing I want is another dammed dongle.
