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)

Ive always had good experiences with Lexar cards and this one is no different. Didnt have any problems with my camera recognizing it, and since my camera takes full sized cards, its more convenient than having to use the adapter and microSD card. Speeds have been great. I have some other cards with similar specs, and this one seems to be just as fast as the others. the v30 is great for taking 4k videos or doing high frame rate videos, where you have to pump a lot of data through the buffers and the card itself. Lastly, build quality is very good, with no issues where it seems like the two halves might separate, or the little fins break off.

Fast, plenty of storage. I use it on my D850. I am able to shoot 7 fps at a full resolution of 45.7 MP. No issues so far.

This is one of the slowest write speeds I have seen with similar specification (SDX V-I 30 U3 C10). the card has big-lettered 1066x 160-MB/s, none of which refers to the write speed, which is where a cards value truly is.

In my pro opinion, these disks are as good as San Disk Extreme Pro. Im an award winning photographer and I depend on good gear including what Im shooting on. I like these Lexar Professional 1066x 64GB disks because they are flawless and Ive never had issue with any of them throughout my career. Ill continue buying these as part of my arsenal.

Lexar is a known brand name, and seeing professional in the product title makes me think this is a higher end Lexar memory card. Perhaps it will last longer, and survive more read/writes before it dies.

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

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