Speed ratings: what you need to know

We recommend Micro SD cards that have at least a UHS Speed Class 1 (U1) rating. This is equivalent to the older Class 10 standard, and means that cards will be able to write at 10 MB/s. The new standard is shown with a 1 in a U symbol; you may also see a 10 in a circle. These cards are capable of recording Full HD 1080p footage directly to the card, as well as giving you more space for songs, photos, videos and apps.

If you would like to record 4K Ultra HD footage directly to a Micro SD card, you’ll need a faster memory card. For this, we recommend a UHS Speed Class 3 (U3) chip, which can support write speeds of at least 30 MB/s. This will also reduce the time it takes to copy media files to and from the card, whether you’re talking about songs, photos or videos. Apps installed to the Micro SD card will also launch faster, so if you don’t want to wait around then a UHS Speed Class 3 memory card is your best bet.

  1. Hi Lydan yes the note8 does support U3 speeds. According to a YouTube video I saw the s8 was using a evo plus micro sd card and it ran androbench benchmark and it showed that the s8 was able to run at about 60 MB/s seq read and 49 MB/s seq write. That’s well over the U3 speed of minimum 30MB/s. The galaxy note3 micro sd slot speed was only 20MB/s seq read and write now it’s good to see that it’s beyond that speed.

  2. because if you read around on the web, it appears smart phones have been quite lacking in the SD card controller side of things for a long time, not supporting UHS at all as far as i know. Even though the modern SD cards are fast, the controllers in our phones do not support the maximum speeds of them
