Samsung PRO Plus 128GB microSDXC card

The Samsung PRO Plus is a 128GB microSDXC card rated UHS-I U3, Class 10, A2 and V30. It delivers sequential read speeds up to 180MB/s and write speeds up to 130MB/s. The card ships with a full-size SD adapter for broad device compatibility.

Ideal for 4K capture and app-heavy devices

Creators recording 4K video on drones, action cameras or smartphones benefit from the sustained V30 write performance. The A2 rating supports faster app loading on tablets and handheld consoles. Users needing maximum capacity beyond 128GB or higher sustained throughput for professional cinema workflows should consider larger or faster media.

UHS-I U3 V30 speed class ensures 4K readiness

The V30 rating guarantees a minimum 30MB/s sequential write speed, the threshold for reliable 4K video recording. Combined with U3 and Class 10 marks, the card meets the speed requirements of most current consumer 4K devices. Six-proof protection adds durability against water, temperature, X-ray, magnetic fields, drops and wear.

Questions about this item

How can I verify the card is performing at the rated 180MB/s read and 130MB/s write speeds after setup?

Use a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader to confirm sequential read and write results match the 180MB/s and 130MB/s specifications.

What is included in the package and what must be purchased separately?

The box contains the 128GB microSDXC card and a full-size SD adapter; a UHS-I card reader or compatible device slot is required separately for data transfer.

Which capacity should I choose among the 128GB, 256GB and 512GB versions?

Select 128GB for light 4K clips and apps, 256GB for extended 4K recording sessions, or 512GB for maximum high-resolution video and game storage.
