Professional photography storage

The ADATA Premier Pro 128GB SDXC card is built for high-end DSLR and mirrorless cameras that require sustained write performance. It carries UHS-I U3 and V30 ratings, making it suitable for 4K Ultra HD video recording and continuous burst photography. The 128GB capacity provides ample space for extended shooting sessions.

Simple card-slot installation

Insert the card into any compatible SDXC slot; no drivers or software are required. The card is ready to use immediately after formatting in the camera. The most common issue is using the card in a device that only supports SDHC, which cannot address 128GB, or in a reader limited to UHS-I speeds below the V30 threshold.

Verify host device compatibility

Confirm that your camera or recorder explicitly supports SDXC cards and the V30 video speed class. Check that the device firmware is current, as older bodies may not recognise the full capacity or sustain the required write rate. Ensure your card reader or workflow hardware can handle UHS-I transfer speeds up to 100MB/s read and 85MB/s write.

Questions about this item

How can I verify the card is delivering the rated 100MB/s read and 85MB/s write speeds after I start using it?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader; sustained sequential results near 100MB/s read and 85MB/s write confirm the card is performing to spec.

What accessories are included with the 128GB Premier Pro SDXC card and what must I purchase separately?

The package contains only the memory card; a UHS-I compatible card reader or camera slot is required for data transfer and is sold separately.

Which speed class should I choose for 4K video on a high-end DSLR — U3, V30 or Class 10?

All three ratings are present on this card; V30 guarantees 30MB/s minimum sustained write for 4K, U3 provides the same floor for UHS-I devices, and Class 10 covers Full HD — any will work, but V30 is the strictest video assurance.
