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 Galaxy 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 which is the best Galaxy S9 microSD card? Without a doubt, these are the very best ones you can get.
Best overall pick
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.
Best on a budget
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 an excellent affordable option.
Durable and fast
Double your phone storage with the 64GB SanDisk Extreme, an ideal card for capturing HD video with high data transfer speeds.
The 200GB Sandisk Ultra is the perfect microSD for anyone looking for that Goldilocks storage option between 128GB and 256GB.
Most space possible
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?
Can take a beating
With an IPX7 waterproof rating, this ultra-rugged card is also shockproof and can withstand extreme temperatures.
Pick the best microSD card that's 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 Galaxy S9 microSD card. While this certainly doesn't apply to everyone, we think that the Samsung 128GB EVO Plus is the best microSD card for the Samsung Galaxy S9. 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 the 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.
While you're at it, don't forget to look into some other Galaxy S9 accessories worth getting to use alongside the phone. And, of course, pick up that all-important protective case for the Galaxy S9 as well.
