Capacity and class for everyday capture

The Samsung EVO Plus microSDXC card delivers 128 GB of storage rated at UHS-I, U3, Class 10, A2 and V30. It targets phone, tablet, action-camera and handheld-console owners who need reliable space for apps, photos and 4K UHD video. An SD adapter is included for use in full-size slots.

Stepping up from slower or smaller cards

The jump is worth it when your current card tops out at Class 10 or U1 write speeds, or when 64 GB forces frequent offloads. Sequential reads reach 160 MB/s, while write rates scale to 80, 100 or 120 MB/s depending on capacity, clearing the buffer faster for burst shooting and 4K recording.

128 GB headroom for mixed media

At this capacity you can store hours of 4K UHD footage alongside thousands of RAW photos and large game installs. The limit appears when projects demand sustained write throughput above the card's variable ceiling or when total library size pushes toward the 512 GB or 1 TB models in the same series.

Questions about this item

Does the 128 GB card ship with the SD adapter shown in the photos?

Yes, the EVO Plus microSDXC card includes a Samsung SD adapter so it can be used in any full-size SD slot.

Which speed ratings are printed on the card to confirm 4K UHD and app performance?

The card carries U3, Class 10, A2, V30 and UHS-I markings, guaranteeing sustained 30 MB/s write for 4K video and A2 app speed.

How often should I reformat the card to maintain the 160 MB/s read speed over time?

Reformat in the host device every few months or after heavy write cycles; this clears stale blocks and keeps read performance near the 160 MB/s spec.
