![]() Random speed: A microSD card used for operating systems, applications, or games needs to be fast at reading and writing small bits of data in random locations.Sequential writes are important for shooting video and high-resolution photos, and copying media to the card. They’re important for watching movies, loading game levels, or copying data from the card to your computer. Sequential speed: Sequential reads show how fast big chunks of data can be read from the card.It also helps to get a reliable card from a reputable manufacturer like Samsung, SanDisk, or Kingston to minimize the chances of something going wrong. Although we didn’t eliminate cards for having a shorter warranty, we noted ones that offered 10-year limited and lifetime limited warranties. Warranty: The longer the warranty, the better.All our picks are UHS-I we didn't test any UHS-II cards because few devices need them, and UHS-II cards are very expensive. You won’t get the full speed of UHS-II unless both device and card have support, because it requires an additional row of physical pins to achieve its extra speed. You should get a UHS-I bus card, unless the device you’re using specifies that it supports UHS-II. UHS-I bus mode: Bus mode is a standard that dictates how different generations of SD cards work.V60 and V90 microSD cards, which are fast enough to record 8K video, are expensive and require relatively rare UHS-II bus devices, so we didn’t test any. Cards rated U3 or V30 have a minimum sequential write speed of 30 MB/s, enough for 4K video. Class 10 or U1-rated cards can write sequential data at least 10 MB/s-the bare minimum for shooting 1080p video. ![]() Unless your device specifically requires a lower speed class (such as Class 2, 4, or 6), you should look for a card rated U1 or U3.
