Samsung 256GB Micro-SD Card
Samsung's Galaxy Note 9 has twice as much storage as any other Samsung phone, with 128GB built in. So while you probably don't need any more storage, if you do, get a nice 256GB card.
Getting Samsung's official 256GB Card will give you nearly 400GB of space in the Galaxy Note 9. It has fast read/write speeds, high ratings and works great with smartphones. We recommend getting this for your phone instead of spending more on the 512GB model.
