SanDisk Extreme PRO microSDXC 256GB 170MB/s 90MB/s V30 A2 U3 Class 10 memory card

High-capacity microSDXC card for 4K capture

The SanDisk Extreme PRO microSDXC card delivers 256 GB of storage with read speeds up to 170 MB/s and write speeds up to 90 MB/s. It carries UHS-I U3, V30 and A2 ratings for sustained 4K UHD video recording and fast app loading on Android devices. An SD adapter is included for broader device compatibility.

Check host device slot and speed class support

Verify that your smartphone, action camera or drone accepts microSDXC cards up to 256 GB and can utilise UHS-I speeds. The card requires a host that supports the U3 and V30 speed classes to guarantee minimum write performance for 4K footage. Older hardware limited to SDHC or lower speed classes will not achieve the rated throughput.

Rugged proofing and daily handling

The card is temperature proof, water proof, X-ray proof and drop proof, protecting data during outdoor shoots and travel. Its compact microSD form factor fits directly into action cameras and drones without adapters, while the bundled SD adapter allows quick offload to laptops or card readers. No moving parts mean silent, reliable operation in vibration-prone environments.
