Lexar Professional 1066x 64GB SDXC UHS-I Memory Card SILVER Series, C10, U3, V30, Full-HD & 4K Video, Up To 160MB/s Read, for DSLR and Mirrorless Cameras (LSD1066064G-BNNNU)

So far Ive own three SD cards made by Lexar and Ive never encountered any issue with them so far. Writing and reading speeds are ok for using with my Nikon DSLR. Nice purchase.

Theres no case with this. That may not be important. It doesnt really bother me about speed; it works. I may not be giving it a fair test, either. Copying some video files from my laptop to this card, my computer showed it with a write speed of 25 MB/s. But overall, it seems like a nice card.

Picture quality is amazing... it could hold up enough pics for a full day photoshoot.

As a casual photographer who takes photos of friends, their kids, family, and some weddings, I am always in need of a card that will hold lots of pictures. This card is now the card I start with because it holds so many pictures. When shooting for short events, this card lasts the entire time. Pictures transfer easily. Overall really love this card and the freedom of not having to worry about the number of pictures I am taking.

This is a decent card, especially if your camera supports the write speed (70MB/s) and doesnt support UHS-II. Sadly, many would likely buy into this thinking 150MB/s might represent the write speed. However, like everything out else out there, this means up to the said amount for speeds in general (aka, read speed). A write speed of 70 though is still pretty good for many cameras.

Great purchase, swift recording and capacity

If you need to replace these under warranty dont count on it. I have 4 defective cards which cant record in 1080p without a write error and instead of replacing them Ive been told to destroy them and they will refund me 20% of what I paid. Ive trusted Lexar for 15 years. Time to move on.

Transfer speeds are decent for a non-SSD and it looks/feels durable.

Im very pleased with my new set of Lexar cards. Lexar is my go-to for photography. To format my new set (in-camera, of course), I needed a firmware update for my D810. On the day, my new set of Lexar cards seemed to write faster than my older set and performed flawlessly.

I picked this up to use as an additional card for my Micro 4/3 camera. I take alot of pictures and high res high fps videos on trips and easily eat up my memory cards. This card worked fine in my camera and didnt have an issue with 4K60Fps recording. However for the max bitrate on 4K I have to use 30fps (150mb/sec bitrate) and it works with that one too.
