SD cards are mostly plug-and-play, but you should know a few things to make the most of yours.
After a short blip with the Galaxy S6 series, Samsung is back to making a microSD card slot one of its core tenets. The Galaxy S8 and S8+ have an SD card slot that lets users choose just how much storage they want to add, even though fewer people will need one with the new higher default storage of 64GB internally.
Whether you’ve already purchased and installed your microSD card or are trying to learn a bit more about them before getting one, we have you covered. Here’s what you need to know about the microSD card slot on the Galaxy S8 and S8+.
Adoptable storage isn’t here — and that’s OK for most people
Sticking with its legacy of devices, Samsung is continuing to use the SD card as removable storage rather than the newer “adoptable storage” system. What that means is that instead of integrating the SD card into the internal storage, it remains its own separate volume. You have to choose to put a file either on the SD card or the internal storage — it won’t be able to span the two seamlessly, which takes a bit more management.
In practice, this has the benefit of being more familiar to those who used SD cards in previous Samsung phones or have used them typically with computers or cameras. You can remove the SD card from a Galaxy S8 freely without worrying about how it will affect the system, because you only lose the data files on the card. You can pop out the card, put it in your computer and transfer files to and from it, then put it back in the phone with no worries.
Not every app can be moved to the SD card
One of the downsides of using the SD card as removable storage rather than adoptable storage is that there are limitations on what files can be moved. For the most part, you can think of the SD card as a place to store big chunks of data, not live applications that you need to access regularly.
You can have photos, music, videos, podcasts, and documents all stored on your SD card without issue, and those are great ways to free up space on the faster, more versatile internal storage. But you won’t be able to move most apps or games to the SD card, as they need to be on the internal storage in order to run. You may find that some simple apps or assets for apps that don’t need to be run on demand can be stored on the card — but as a rule, you shouldn’t count on being able to move apps to the SD card.
