The Samsung Galaxy S7 is one of the most popular smartphones on the market, and for good reason. It’s a great phone with a lot of features. One of the features that makes it so great is the fact that it has a micro SD card slot. This means that you can expand the storage on your phone by adding a micro SD card.

If you’re going to add a micro SD card to your Galaxy S7, you need to make sure that you get the right size. The last thing you want to do is get a card that is too small or too large. In this article, we will answer the question: What size micro SD card for Galaxy S7?


The capacity of a microSD card measures how much information it can store. This is represented in digital information units known as bits (e.g., 8GB = 8,000,000,000 bits). The larger the capacity of the microSD card, the more information it can store.

There are two types ofcapacity: nominal and real. Nominal capacity is the amount of space advertised by the manufacturer. Real capacity is the amount of space actually available to store data. For example, a 32GB microSD card might have a nominal capacity of 32GB but a real capacity of only 29GB.

When shopping for a microSD card, be sure to check the real capacity to ensure you’re getting what you expect.

Speed Classes

When shopping for a microSD card for your Galaxy S7, you’ll want to make sure to get one with the right speed class rating. The two main classes you’ll see are Class 10 and UHS-I.

Class 10 cards are the minimum speed class rating you should get for any modern device. This means that they guarantee a minimum sustained write speed of 10MB/s. They’re fine for most uses, including Full HD video recording and everyday storage, but if you want to do anything more demanding, like 4K video or high-speed burst shooting, you’ll need a card with a higher rating.

UHS-I is the next step up and offers guaranteed write speeds of at least 30MB/s. These cards are ideal for 4K video and high-speed burst shooting. If you’re planning on doing any serious video work with your Galaxy S7, a UHS-I card is worth the investment.

UHS Speed Classes

When shopping for a microSD card for your Galaxy S7, you’ll want to pay attention to two things: capacity and speed. Capacity is how much stuff you can store on the card, while speed is how fast it can save or load that stuff.

The Galaxy S7 uses a Micro SDXC card, which means it’s compatible with cards up to 2TB in capacity. However, cards that large aren’t widely available yet, and probably won’t be for a while. For now, the largest capacity you can get is 256GB.

As for speed, the Galaxy S7 supports UHS-I speeds up to U3. That means it can take full advantage of cards rated for 90MB/s write speeds and 95MB/s read speeds. If you see a card advertised as “Class 10” or “U1,” that means it’s fast enough for the Galaxy S7.


The right size micro SD card for the Galaxy S7 depends on what you plan to use it for. If you just want to store some music and photos, then a 32GB card should be plenty. If you want to store a lot of high-quality video, then you’ll need a 64GB or 128GB card. And if you plan to use your phone for virtual reality gaming, then you’ll need a 256GB card.
