While many folks will make due with their device’s internal storage, there are just as many who feel they could use a little breathing room. It’s important to choose a nice microSD card for your smartphone no matter what you want to use it for.
Today, we’re presenting what we feel are some of the best options for speed, capacity, and reliability. Check out the best microSD cards for the Galaxy S9 and S9+ straight ahead.
If you just want to cram as much storage inside your phone as you can, get the 400GB SanDisk Ultra card. With transfer speeds up to 100 megabytes per second you’ll be able to get all of your photos, music, and videos back and forth without too long of a wait. This is probably the most expensive card on the market, but it’s here if you need it.
We wish our reasoning for this selection were as simple as “well, you’ve gotta buy Samsung for Samsung,” but it’s even more than that. Samsung just makes damned good microSD cards, and the EVO line is perhaps the most trusty out there. UHS-3 Class 10 performance makes it perfect for apps, games, and all your multimedia, and Samsung says this thing is a lot more reliable than the competition thanks to its “4-proof protection.”
Designed specifically for handling 4K video, the SanDisk Extreme line includes a new Video Speed Class rating, with 30 being the highest. A standard UHS-3 speed rating also puts it in line with any top card today, delivering a consistent experience for all your needs.
