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.
Samsung’s EVO Select micro SD card is a great option to use with the Galaxy S9 and S9 Plus. This is the 64GB model, which is going to basically double the storage in your Galaxy S9, and allow you to take more images, store more music offline and just have more storage altogether.
Samsung’s EVO Plus lineup is also a great lineup to choose from. This is the 128GB capacity card, and it sports 100MB/s read and 90MB/s write speeds. That’s not the fastest out there, but pretty close. This does mean that you will be able to record 4K footage and even slow-motion footage to the SD card without any issues, really.
SanDisk is the leader in the world of micro SD cards and storage, and this micro SD card is one of the fastest out there. It sports read speeds of around 275MB/s and write speeds of around 100MB/s. That is pretty insane, and likely even faster than the flash storage inside the Galaxy S9.
If you are looking for a fairly decent micro SD card, speed-wise, but need a lot of storage. This is the one for you. 400GB of storage should be more than enough for most people, and this is also the largest capacity micro SD card available right now.
Looking for slightly faster speeds, but still a high capacity card? The 256GB model here is worth looking at. This one sports 100MB/s read speeds and 90MB/s write speeds, which is going to be plenty for recording 4K and super slow-motion video, but it also has A1 support, which makes it great for saving apps and games to the micro SD card.
If you just need a bit more storage, and also don’t want to spend a ton of cash, this is a great SD card to pick up for the Galaxy S9 and/or the Galaxy S9 Plus. This one sports 32GB of storage, but isn’t super fast like the others on this list. However it does include a regular SD card adapter.
The EVO Plus from Samsung is another great option, with 256GB of storage here, you’ll have plenty of space for really taking advantage of the Galaxy S9’s camera. Additionally, it does sport 100MB/s read and 90MB/2 write speeds, which is also great to see here.
This one here is slightly cheaper than the previous 256GB micro SD card from Samsung. It is actually optimized for recording 4K content, so it’s going to be a great fit with the Galaxy S9’s camera, especially for recording video in 4K at 30fps.
Those that just need a tad bit more storage, the SanDisk Ultra 32GB model is going to be a great option. Especially since it is indeed just under $15, that’s not a whole lot to spend for some extra storage on your Samsung Galaxy S9 or Galaxy S9 Plus.
This one will also double the storage in your Galaxy S9 or Galaxy S9 Plus, and it’s part of Samsung’s Pro Select series, which means that it is optimized for content creators. Meaning its great for recording video, taking photos and even recording some audio.
