Best MicroSD Cards for the Galaxy S8



The Samsung Galaxy S8 and Galaxy S8+ support microSD cards so you can increase the storage on your phone. While 64GB of storage built-in is usually enough for most, others will want extra space for music, movies, video or photos. With that in mind, these are some of the best microSD cards for the Galaxy S8.

Our buyers guide will go over everything you need to know about microSD cards. Some cost under $20 and will give you a little extra space, while others cost a lot more but deliver improved performance and tons of storage options.

Many Galaxy S6 or S7 owners were frustrated when they ran out of space, but that isn’t a problem for the Galaxy S8. The phone has twice as much storage built-in, and by using one of our recommendations below you can add over 300GB of total space. That’s more than enough for most.

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 12MP camera. And if you want to record 4K video, a microSD card is probably a good idea.

Another reason you might want to get a microSD card is for improved performance. Some of the options in our slideshow below have extremely fast speeds. This helps apps run smooth, games open quicker, and HD video recording more seamless. Those are on top of the obvious storage increase benefit.

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. Most retail stores like Verizon, AT&T or even Best Buy are extremely overpriced, so don’t buy one there. 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.

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.

Our recommendation for most owners would be a 64GB card, as it’s a nice middle ground. Most are plenty fast but if you want the best performance you’ll be paying a little extra. Whether you’re a power user that needs 300GB or just want extra room, take a peek at our favorite Galaxy S8 microSD cards below.

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 recommend only getting a card that is "Class 10" or says "UHS-1 or UHS-II" 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. 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.

    A1 sd card means the card handles an input-output access per second of 1500 and write files at a third of that speed. We can store apps, files, photos, videos, and documents. It can quickly open apps and process accompanying tasks. Last year I brought a San Disk memory card from an online store like “Mobansp” have the huge collection on this but I think this one is helpful for us.
