Lexar Professional SILVER Series 256GB CFexpress Card, Type B CFe Card up to 1750MB/s Read, CF Card Adopt PCIe Gen3x2, CF Memory Card Compatible with DSLR, Backward with XQD Camera (LCXEXSL256G-RNENG)

Works brilliant with clear CF card. So fast it blows me away. Literally

works very well does the job quality looks and feels good

Excellent card, easy to format and with a Nikon Z8 at highest picture quality and raw you can take 11k pictures or for 4k 30fps video at 10bit you can take 10hours of video. Doesn't slow down when writing large volumes of pictures or high quality video to card.

my camera is going heat up with this card

Having recently added a Nikon D850 to my kit bag, it soon became apparent that I couldn't get away with simply using an SD card. For video and high speed continuous, shooting would grind to a halt very quickly with an SD card. Like it or not, I knew I'd have to bite the bullet and buy a high speed CFExpress card.Now having done a little bit of research, it soon became apparent that QXD cards are old hat. If you want the latest (and fastest) you need CFExpress. Now Lexar has always had a very good reputation for memory cards so I was keen to see what they had to offer. Looking around, it soon became apparent that high speed, premium brand CFExpress cards don't come cheap - a 128GB card is still around £170 if you want a decent branded card. You can therefore imagine I jumped pretty quick when I saw that the Lexar 128GB card being sold everywhere else for £170 was only £132 on Amazon. That's a big saving!The card arrived next day in small retail packaging with the card itself safely stored within a plastic card case. Sticking the card into my Nikon D850, the first thing I tried was continuous high speed shooting - I set the camera to full resolution, non-compressed RAW and hit the shutter release. The camera started cranking through shutter actuations like an MG-42 on full automatic with no sign of slow down. After about 20 seconds or so, it was STILL going with no slow down at all.Now Lexar quote a maximum write speed of 1750 mb/s but of course what really matters is sustained write speed. This is where cheaper brands normally fall flat on their faces but not the Lexar - it manages to achieve a good 1000 mb/s sustained which should be fast enough for 99% of people shooting uncompressed video and RAW files.RAW files from a D850 aren't small - each image from my little test above was about 56 mbytes so you can imagine that 9 frames per second for 20 seconds is going to produce a lot of data! 180 images at 56 mbytes per image = over a Gigabyte of images! Transferring all that data needs a high speed memory card reader so don't hesitate to buy a decent CFExpress USB-C (or similar) card reader if you haven't got one already!My little review really has only scratched the surface of the capabilities of this card. As you can tell, I’m impressed. It’s fast. In fact, it’s insanely fast. Is it the fastest card money can buy? Not quite - even Lexar’s own Diamond series cards are faster - but most people will find the Lexar professional series more than adequate for their needs. Only really problem is choosing which capacity to buy - I bought a 128GB card and even now wish I’d gone for the 256GB or even the 512GB!

Works really well and is plug and play

Using this on my Nikon Z9 without any issue.

I ordered this as a backup CF express reader ( my main reader is an Alxum which has worked perfectly for several years). I tried the Lexar (with a Lexar CF card) on both an Apple MacBook pro and and Apple iMac. It loads onto the desktop but wills not open files on Photoshop. I’m a pro photographer - so cannot trust this device.
