With 64GB of space built-in, most Galaxy S9 owners won’t need a microSD card. However, if you have a lot of movies and music, or plan on shooting tons of 4K or slow-mo video, a microSD is highly recommended. Some cost upwards of $150 and deliver class-leading speeds or over 300GB of storage. We’ll also recommend some affordable 64GB cards that won’t break the bank.

Improving performance is one of the main reasons to buy a microSD card. They help apps run smooth, games open quicker and even improve 4k video recording or playback. Along with the obvious increase in storage limits. As a result, the fast microSD cards in our roundup will do exactly that.

One of the biggest problems is all the different sizes, speeds, brands, and prices.

MicroSD cards are extremely affordable these days, meaning there’s no reason not to buy one. They’re no longer $200-$300 like they were a few years ago.

As a result, our first recommendation is a 64GB card. You can get one for less than $25 and it’s all most owners will ever need. Giving you a combined total of over 120GB of storage on your Galaxy S9. Keep in mind the actual available space will be less after formatting, apps, photos, and the OS taking space on your device.

Additionally, we recommend only buying a card that is “Class 10” or says “UHS-1 or UHS-II” if you want the best performance. Class 10 gets visualized by a small circle with a 10 printed inside it right on the card. Our image above shows the “U” branding for UHS.

Here in 2018 most should say that or the new “A1” standard.  Samsung’s card delivers these speeds at a wallet-friendly price point. If you buy at the right time, an excellent card like this Samsung 64GB microSD chip can be found for under $20 online, or around $50-75 at local stores.
