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.

Questions about this item

What does the UHS-I U3 V30 rating mean for real-world write speed?

The U3 and V30 markings guarantee a minimum sustained write speed of 30 MB/s, so 4K video recording will not drop frames.

Does the card include an adapter for full-size SD slots?

Yes, the MB-MB128T package comes with a microSD-to-SD adapter so you can use it in cameras, laptops or card readers that only accept standard SD cards.

How do I enable the A2 app-performance rating on my Android phone?

Insert the card, then format it as internal storage in the device settings; skipping that step leaves the card in portable mode and apps will not benefit from the A2 speed class.
