Best Memory Cards Samsung Galaxy S20, S20+

Best Memory Cards Samsung S20, S20+, S20 Ultra

  • January 17, 2021

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

For this guide, we benchmarked most of the popular micro SD cards to see which cards perform the best, but also which cards are the best for each use case.

 

Best Memory Cards Samsung Galaxy S20, S20+, S20 Ultra

Before buying a memory card for andy of the Galaxy S20 series of phones there are a few things you should know.

Like with the previous phones, the Galaxy s20 series can take a micro SD memory card with a capacity up to 1TB.

There are a few classes of SD memory cards now that will do different things. The main thing you need to look for is A1 and A2 cards vs no A rating at all. The A rating is useful if you want to run apps off your card since it will allow for improved read and write performance of small files. Whereas if you’re just copying photos and video, this won’t be important and you won’t gain any benefit of going with an A1 or A2 card.

 

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

Best Memory Card 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.

Card Name Write Speed Read Speed Check Price
Sandisk Extreme Pro A2 128GB 54MB/s 79MB/s Amazon
Sandisk Extreme A2 128GB 55MB/s 78MB/s Amazon
Sandisk Extreme Plus 75MB/s 80MB/s Amazon
Samsung EVO Plus 42MB/s 83MB/s Amazon
PNY PRO Elite 70MB/s 74MB/s Amazon

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.

Best Memory Cards Samsung Galaxy S20, S20+, S20 Ultra Conclusions

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.
