Patriot 256GB LX Series microSDXC Memory Card Review @ CDRLabs.com
 

"Patriot's 256GB LX Series microSDXC card is a great addition to the company's already impressive line of flash memory cards. Thanks to its use of 3D NAND, the 256GB LX Series card provides the capacity that smartphone, drone and action camera users need to capture hours worth of 4K Ultra HD video. Patriot's new microSDXC card is also Class 10, U3 rated and is capable of delivering some impressive performance numbers. In our tests, the 256GB LX Series card was able to read at speeds as high as 96 MB/s and write at more than 81 MB/s."
