The onn 512GB microSDXC card is a budget-priced high-capacity card rated Class 10, U3, V30 and A2, with read speeds up to 100 MB/s and a 30 MB/s minimum write speed. It ships with a full-size SD adapter and is marketed for phones, tablets, cameras, drones, computers and the Nintendo Switch. The V30 and A2 ratings put it in line with mainstream cards for 4K recording and app storage, though its write ceiling is well below premium U3 cards. It suits shoppers who want maximum capacity for photos, video and game downloads at a low cost per gigabyte, not those who need sustained high-bitrate write performance.
