Lexar Professional 633x SDHC/SDXC UHS-I cards let you quickly capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video, with a read transfer speed up to 633x (95MB/s). The cards leverage UHS-I technology (U1 or U3, depending on capacity) for high-speed, Class 10 performance. And when using a USB 3.0 card reader, you’ll power through post-production with high-speed card-to-computer file transfer. This dramatically accelerates workflow from start to finish, so you can save time and get back to the business of photography. Cards include downloadable Image Rescue software, and come with a limited lifetime warranty.

even worse than my old SD cards
Very slow cards on my Canon 5D Mark 3, freeze after continuous shoot for 5 pictures, even worse than my old SD cards. False description, and could not return for full refund.

Can sketch the scene while it writes...
I purchased these as additional backups to my older "Lexar Professional 600x 16GB SDHC UHS-I Flash Memory Card LSD16GCRBNA600" thinking that they would be similar or maybe slightly better performance in my Nikon D7100. Oddly, it turns out that these, unlike their predecessors, are SO much slower when shooting RAW at higher frame rates. The Nikon D7100 has a small buffer. To alleviate some of the pressure off the internal memory I have used both the older Lexar cards mentioned above (also the 32GB models)and the SanDisk Extreme PRO 16GB UHS-I/U3 SDHC Flash Memory Card. All worked amazing. Never had any significant issues or missed a shot. I started using these newer versions and the camera would take three shots and then the frame rate would drop to about 1 frame every 1.5 seconds. With the other cards, the frame rate would drop to about 3 frames per second. That seems like a big difference for a card claiming to have similar or better capabilities to older products. It also seems to read slower than the other cards too. I reformatted the cards in the camera but it made no difference. Not exactly sure why the drastic reduction in performance has occurred, but it is disappointing when compared to older models of this card.

Don't Buy this.
By bassel mattroud
I saw the deal on this card and quickly ordered a couple of those cards to add to memory card arsenal. It was a price too good to be true from a reputable vendor like Lexar. And I thought that some of the negative reviews are simply biased or plain bad luck.
When those cards were delivered, something felt wrong. The packaging seemed to be glued together by hand. And the card labeling also seemed fake. On the backside the write speed mentions 20 MB/second. but on Lexar’s website they are supposed to be 45 MB/second. When I inserted into the computer it gave me a 118 GB of free space but the card read SDXC but no indication of the manufacturer is shown. So most probably are faked SD cards from a shady source.
My recommendation is skip Amazon for any purchase of SD cards and go to more reliable sources like B&H and Adorama. Sure you can save a few bucks on Amazon bu most probably will end up with fake products that don’t give you 10% of what you are paying for it.
