Many Galaxy S6 or S7 owners were frustrated when they ran out of space, but that isn’t a problem for the Galaxy S8. We now have twice as much storage, and the option to add over 300GB in total. If that interests you we have a few recommendations below.

Double your storage in seconds with a MicroSD card

Add as many movies, apps or games as you’d like to your phone. Then fill it with photos from the stunning 12MP camera or record 4K video for playback on the new 5.8 or 6.2-inch Quad-HD Infinity displays. That’s all possible simply by adding a microSD card for additional storage.

With tons of different sizes, speeds, brands and more there’s a lot to consider. An SD card is one of the best accessories one can buy, but make sure you don’t pay too much. Here we’ll share some good options for speed and performance. Then offer up ones with the best price or highest storage limits.

Using the SIM slot removal tool that comes in the box owners can remove the SIM tray, put a microSD card next to it and slide it back in. Instantly adding another 64GB, 128GB or even 256GB of storage in seconds.

It’s worth noting that most retail stores are extremely overpriced, so do not buy one there. Whether it’s Verizon or AT&T, or retailers like Best Buy, most charge too much. Instead get a cheaper microSD from our roundup below. Keep in mind that Best Buy will often price-match retailers, for those that can’t wait for online orders.

Our recommendation for most owners would be a 64GB card, but power users may want even more storage. Without further delay, below are the best microSD cards for the Galaxy S8 or Galaxy S8 Plus.

Just a few years ago a 64GB microSD card would have been extremely expensive and out of reach for many. However, these days storage is really cheap. While some may want to just get an extra 32GB for their phone, it's more cost-effective to get a 64GB card instead. 

For less than $20 you can get a 64GB microSD card and have 128GB of storage on the Galaxy S8. All while being less than buying the highest storage model of the iPhone 7. Keep in mind the actual available space will be less after formatting, apps, photos, and the OS taking space on your device.

We'd recommend only getting a card that is "Class 10" or says "UHS-1" if you want the best performance. Class 10 is visualized by a small circle with a 10 printed inside it right on the card. Our image above shows the "U" branding for UHS-1. In 2017 most should say that or the new "A1".

Samsung's own 64GB EVO+ Class 10 card is first on our list. It's not too big and not too small. All while delivering fast performance for apps or games, and recording high quality video. This is a great way to add more storage than you'll ever need without breaking the bank.

If you do some research, an excellent card like this Samsung 64GB microSD chip can be found for under $20 online, or around $50-75 at local stores. So again, don't over pay.

    Hi Cory,

    What is the UHS Bus speed of the Samsung S8? Everything you mentioned was UHS-I, but I’d like to know specifically if it’s I or II. I’ve used 3 different MicroSD cards (all UHS-I) on my S7 and found that only 1 UHS-I was actually able to handle 4K video and not be very slow holding 100+ GB of files/vids/pics. With UHS-II out I’m looking at upgrading for future tech, but will stick with my UHS-I if the Samsung S8 does not support it.
