Ready for 4K UHD capture

This 256GB microSDXC card carries U3, V30 and A2 ratings, delivering read speeds up to 200MB/s and write speeds up to 90MB/s. It is built for action cameras, drones and Android smartphones that need sustained 4K UHD video recording and fast app loading.

Check host device compatibility

Verify that your device supports the microSDXC standard and can make use of UHS-I speeds; older hosts limited to microSDHC will not recognise the full 256GB capacity. Confirm the slot accepts U3 or V30 speed classes so the card can sustain the advertised write performance for 4K UHD footage.

Durable in extreme conditions

The card is rated temperature proof, water proof, drop proof and X-ray proof, so it withstands harsh environments without active cooling or power concerns. Solid-state operation means silent performance and negligible power draw during normal read and write workloads.

Questions about this item

What comes in the box with the SanDisk Extreme Pro 256GB microSDXC card and do I need to buy an adapter separately?

The card is supplied as a single microSDXC unit; a full-size SD adapter is not included and must be purchased separately if your device requires one.

Which capacity should I choose between the 64GB, 128GB and 256GB versions of this Extreme Pro line?

The 256GB model gives you the same 200MB/s read and 90MB/s write speeds as the smaller cards but four times the space of the 64GB version for extended 4K UHD recording.

What does the 200MB/s read speed mean when I put this card in my drone or action camera?

It lets you offload 4K UHD footage to a computer at up to 200MB/s when paired with a compatible UHS-I reader, cutting transfer time for large 256GB projects.
