Best microSD cards for Android Android Central 2021
You can easily transfer your files, photos and music to your Android phone using a microSD card. You can also load up your Android phone with additional apps, music, movies and other files, especially if you don't have much internal storage. Which ones are the best? These are just a few of the many options available.
What does all this mean for your card?
There are many ways to classify microSD cards speeds. Most cards have at most two of these classifications, along with the straight read/write speeds. Here's a cheat sheet that will help you determine which format is best.
Video Speed Class : Indicated by a stylized V followed by numbers from 6 to 90, this class is one of the newer classification systems and was developed specifically for shooting ultra-high-definition video. V30 is 30 MB/s while V60 is 60 MB/s. V90 is 90 MB/s. However, unless you shoot 8K video with your phone, you won't need a V90.

UHS Speed Class: This class is indicated by a 1, 2, 3, or 3 within a U. It's still used today on most cards. U1 is 10MB/s, U3 is 30MB/s, and both are sufficient for most Android phones.
This class is indicated by a 1, 2,, or 3 within a U. It's still used on most cards today. U1 is 10MB/s, U3 is 30MB/s, both of which are sufficient for most Android phones. This was the original classification system used for SD cards. Speed Class: A number within a C indicates speed. This was the highest class, at 10 MB/s, but almost every card worth purchasing today is much faster than this speed.
These specs are focused on write speed. If you see a card that has a transfer speed of 100MB/s, but only U3 classes, it is likely that the card has a read speed 100MB/s and write speed 30MB/s.
A U1 or U3 card, such as the Samsung EVO Select, will suffice for most users. If you plan to use your microSD card to store large amounts of photos and 4K video, then you may want to invest in a U3/V30 (30MB/s), or V60 card such as the Lexar Professional1000x.
Before you buy, make sure your phone is charged.
