SAMSUNG T7 microSD 128GB 170MB/s U3 V30 A2

128 GB microSDXC for everyday devices

The Samsung T7 microSD is a 128 GB microSDXC card rated UHS-I U3, V30 and A2. It delivers sequential reads up to 170 MB/s and includes a full-size adapter. The card suits casual gamers, amateur creators and everyday users who need reliable storage for photos, 4K video and game libraries across smartphones, tablets, handheld consoles and laptops.

Ideal for single-card workflows.

This capacity works well for people who want one card that moves between a phone, a camera and a gaming handheld. Buyers who need more storage than 128 GB provides should look at higher-capacity options. Users who require sustained write speeds beyond the V30 guarantee or application performance above the A2 rating will need a different class of card.

UHS-I U3 V30 A2 rating defines video

The U3 and V30 markings certify a minimum 30 MB/s sustained write speed, which is the threshold for stable 4K recording. The A2 rating means the card can handle random read and write IOPS required by Android app installs and game loading. If your device or workflow demands a higher minimum write class or a faster bus interface, this card will not meet that requirement.
