Best Memory Cards Samsung S20, S20+, S20 Ultra

To keep true to the Galaxy, Samsung kept alive the ability to expand the storage with a micro-SD memory card slot. 

I’ve compiled a massive list of benchmarks with a few recommendations from all the most popular SD cards tested with the Galaxy phones. See the results to find the best memory cards for your needs.

Like the previous phones like the S10 and S10+ Samsung has kept the micro SD memory card slot in the smartphone so that you can add your own micro SD memory card to expand the storage with a capacity up to 1TB.

There are a few things you need to know before buying memory cards.

There are A1 and A2 micro SD memory cards specifically designed to run applications. If you want to expand the storage of your Galaxy and run apps off the card, you should buy the A2 memory cards. If you just plan on using your phone for storage for photos and videos, then it doesn’t matter.

Top 5 Recommended SD Cards Galaxy S20, S20+, S20 Ultra

I’ll list a few of the fastest performing memory cards that I tested in the S10+ with both A2 specs and without. The Galaxy phones do not yet use UHS-II technology so there is no reason to buy the more expensive UHS-II cards.

The Read and Write speeds listed here come from the Galaxy S10+. If I get a chance I’ll retest in one of the S20 phones.

I have listed here 128GB cards, but you can buy cards up to a 1TB capacity. Some people even like those 400GB Sandisk cards. The bigger cards should match a similar performance as the 128GB cards I’ve tested here, so just be sure to match the card.

Memory Card Benchmarks

I benchmarked each memory card in the Galaxy S10 to get the read and write speeds using Disk Speed Test for Android. Here are the results.

Since you’ll likely be using the S20 additional storage for photo and video, here are the photo/video related spec for each camera.

Expanding your storage on the Galaxy S20 line of phones shouldn’t be too complicated.

You have a maximum capacity of 1TB, then you just have to decide to go A2 or standard non-A cards. After using an A2 card in my S10+ for a year I have to say, that I’ve never noticed the slower transfer speeds compared to faster non-A cards, and I have the peace of mind knowing that my apps that I load onto my card (if I ever do such things) perform at their maximum performance.
