The Galaxy Note 9 comes with a hefty amount of storage with the base model at 128GB, but if you want to get more with the 512GB variant, you need to cough up another $250. Thankfully, you don't have to splurge for the 512GB Note 9 just to get more storage space. Instead, you can pick up a microSD card for a lot less money and still give yourself some more wiggle room.

Some people may just need a little extra wiggle room with the 32GB card, and while we can't imagine anyone will fill up the Note 9's internal space and then need another 400GB, it's nice to know that all of these options exist. For most folks, the SanDisk Ultra 64GB microSDXC Card will be the best pick thanks to its great balance of speed, increased storage space, and price.
