OCPC microSDXC/microSDHC card is a tiny memory card, same size as a standard microSD, but with eXtended Capacity, meaning it holds more data (over 32GB, up to 2TB) and uses the exFAT file system, making it ideal for high-resolution photos, 4K/8K video, drones, and action cameras, offering larger storage for demanding devices than older microSDHC cards.
