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.

The price…

Just tested this on two computers. both were getting about the same speed. Not as advertised, but not terrible. was getting 90MB read speeds and 65 MB write.

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

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.

El producto es excelente, ya lo instale en mi cámara sony A6400 y cumple con sus especificaciones.

I bought this card for a game camera which constantly fills lesser storage cards. Im impressed with how fast images on the card roll through my image viewer. Lots of more expensive, lesser storage cards Ive used before would cause the image viewer on my computer to go grainy or lock up. This card can manage the viewer as fast as it can change images.

I currently shoot with at least five (5) bodies, Nikon D800, Nikon D610, two Nikon D700s and Nikon D2Xs. I shoot a lot of photojournalist shots and need my cameras to keep up with the action and record the data without fail. I miss a shot and the opportunity is gone forever. I have be relying on Lexar Professional storage devices for more than 15 years and have yet to have one fail me. This particular model had breathed new life into my D610 it records extremely fast and with a Thunderbolt reader attached to my Apple Studio, the download time is cut significantly. These are my Go To storage devices and will be for the foreseeable future. Highly recommended.

Lexar cards have never let me down. Although I do toss out my SD cards every 2-3 years, Ive never had issues with any of their stuff. The read and write speed is fast enough for my A7ii and files are easily transferable to my Mac.
