Super Fast CFexpress Type B Card
Capacity: 128GB Style: Old Version
Review Image by jordan
Review Image by jordan
As far as I can tell these are real and legit. Works perfectly in Canon R6iii. Works as you would expect. Super fast read and write speeds. I offloaded 37GB of video within 3 minutes which was insane to see. No v60 or v90 sd card could do that. This little thing does heat up pretty fast. You would be surprised how hot it gets after a heavy load of usage. Price is definitely a huge negative but we all know memory storage prices are completely out of control. I would buy this again no problem since quality and performance is top notch. ... show more

Excellent CF-Express card.
Capacity: 512GB Style: Old Version
Works perfectly with my Canon EOS R6 Mark III mirrorless camera. It allows you to increase the size of the buffer considerably when shooting in. burst mode. Got a terrific low cost reader by Acer to attach to my Mac- works perfectly. Works well with Windows too though, not sure it will work as perfectly open that platform, but it should. I took 7K video with this and there wasn't so much as a hiccup. These cars do get a little warm though, but that's normal. ... show more

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. ... show more

CFexpress Cards will not work in all readers, pls read
Capacity: 128GB Style: Old Version
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. ... show more

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. ... show more

Blazing Fast and Reliable — Just a Bit Pricey for Casual Users
Capacity: 128GB Style: Old Version
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. ... show more
