Speed and Capacity was amazing. Also, for video V30/U3 makes it suitable for sustained video recording, including demanding 4K workloads.

I love this memory card.It doesn't lag or freeze up like most others I have used and it doesn't keep telling me to format my memory card until everything i had on it is lost.I use it for a backup for my home security camera I can record hours on this memory card 256g holds alot of memory.its not built cheap it is reliable.i would recommend this micro to anyone it has great compatibility and stands on its durability.
I would recommend this to a friend!
