With options for 64GB, 128GB, and 256GB in storage, the Samsung Galaxy S9 has you covered no matter what you need. However, should you buy the phone and realize you need more space after the fact, the S9's microSD card slot makes it easy to upgrade your storage at any time. There are a ton of microSD cards out there to choose from, but without a doubt, these are the very best ones you can get.
Even the base 64GB Galaxy S9 offers plenty of space out of the box, so if you just need a bit more wiggle room, 32GB is a really good affordable option.
Double your phone storage with the 64GB SanDisk Extreme, an ideal card for capturing HD video with high data transfer speeds.
Samsung's Evo Plus is the best option for most people. The 128GB card delivers 100Mb/s read speeds, and 90Mb/s write speeds at a great value.
The 200GB Sandisk Ultra is the perfect microSD for anyone looking for that Goldilocks storage option between 128GB and 256GB.
Samsung offers card sizes of all sorts for phones like the Galaxy S9, but one of the best deals currently offered is for this 256GB microSD.
With 512GB, you can store up to 100,000 18-megapixel photos or 80+ hours of full HD video. How much more storage could you possibly need?
Pick the card thats right for you
When it comes to microSD cards, your usage and habits are the most significant factors in deciding which one is the best overall fit. While this certainly doesn't apply to *everyone*, we think that the Samsung 128GB EVO Plus is the best choice for most people. In addition to the S9's built-in 64GB, this gives you a combined storage allotment of 192GB. That should be more than enough space for all of your apps, games, photos, and movies.
At the same time, don't buy more storage than you really need. If you just need a little more wiggle room and want to spend as little as possible, go ahead and pick up Samsung 32GB EVO Select. It'll give you an excellent storage boost and only costs a few bucks.
Should you need *a lot* of storage, we'd recommend the Samsung 256GB EVO Plus over the 512GB PNY option. Samsung's card will give you a total storage amount of 320GB after you factor in the Galaxy S9's base storage, and even for people with a lot of local files, we don't imagine you'll fill that up anytime soon.
