A few years ago, when Samsung truly overhauled its design, it opted to remove the micro SD card slot. Something that Samsung smartphones had since the beginning of Android really. It was met with quite a bit of lashback from customers and the media. So Samsung brought it back in the Galaxy S7 and it has been here ever since. The micro SD card slot is a great way for customers to go ahead and expand storage on their smartphone, without having to pay a $100 premium to add 32GB of internal storage to their device. But the real question here is which micro SD cards are worth buying for the Galaxy S9 and Galaxy S9 Plus? There are a ton of them out there, and some perform better than others, and some are also counterfeit versions that will like die pretty quickly. So we rounded up the ten best micro SD cards currently available.
For those looking for a high-capacity micro SD card, the SanDisk Ultra 400GB micro SD card is definitely the best option. As expected, this does offer up the highest-capacity available right now, at 400GB. That means you'll get around 390GB of usable space available to you. That's still a ton of space, and will be plenty of room to record a ton 4K video, even at 30fps. Also plenty of room for shooting some super slow-motion videos at 960fps. The SanDisk Ultra lineup does sport read speeds of 100MB/s and write speeds of 90MB/s.
Another good option is really anything in Samsung's EVO Plus lineup. Which consists of most storage capacities, including 64GB, 128GB and 256GB. These are great because they do sport the same read and write speeds as the SanDisk Ultra model, 100MB/s and 90MB/s respectively, but they are optimized for recording video. And where the Galaxy S9 is really good at recording video, and doing slow-motion video, it makes these cards a great choice. All of the micro SD cards below are great choices for those looking to add some more storage to the Galaxy S9 or Galaxy S9 Plus, and it's hard to go wrong with any of them. But make sure the one you do buy, is from a reputable company like Samsung, SanDisk or Kingston, as others are likely to be counterfeit.
