Samsung 64GB EVO+ Class 10
Being a bit more realistic, as not everyone needs 200GB of space, a high-speed 64GB card will be enough for 95% of users. That will give you 64+32 for around 96GB of total space. 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" 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 2018 most should say USH-II or "A1". Some more expensive cards will even have a small II printed in the bottom right corner. This is the absolute fastest UHS-II rating.
Those who just want extra space should consider Samsung's own 64GB EVO+ Class 10 card. It's made by Samsung and goes perfectly with the Galaxy S7. It's not too big and not too small while delivering fast speeds and great performance. This is a good way to get extra space without breaking the bank.
If you do some searching, an excellent card like this Samsung 64GB microSD chip can be found for around $20 online, or over $50-75 at local stores. So again, don't overpay.
