Review on SanDisk Mirrorless SDSDXXG 256G GN4IN Everything Stromboli Computer Accessories & Peripherals in Memory Cards by Bogdan Shahanski ᠌

Its pros: Corresponds to the declared category V30, records video 100Mbps without problems. Relatively low price. Year of use - normal flight. Has some cons: The advertised read/write speed of 170/90 isn't even close. Real speed 80/30 for reading / writing. Thus, the write speed is minimal for the V30 standard.
