256GB microSDXC for action cameras

The SanDisk Extreme microSDXC card provides 256GB of storage in the UHS-I form factor. It carries U3, V30 and A2 ratings, making it suitable for 4K UHD and Full HD video capture on drones, action cameras and smartphones. An SD adapter is included for use in full-size slots.

Sustained write performance for long clips

The card is rated for up to 90MB/s write speed, which supports continuous recording at the V30 class minimum of 30MB/s. This allows extended 4K sessions without frame drops caused by buffer overflow. Read speeds reach 160MB/s for rapid offload to a computer when the host device supports UHS-I.

Rugged build with recovery software

The card is temperature-proof, water-proof, shock-proof and x-ray proof for reliable operation in harsh environments. SanDisk Memory Zone app simplifies file management on Android devices. A one-year RescuePRO Deluxe download offer helps recover accidentally deleted photos and videos.

Questions about this item

Does the SanDisk Extreme 256GB card run hot or draw extra power during all-day 4K recording?

The card is rated temperature-proof and draws only the standard microSD bus power; no active cooling is needed for continuous U3/V30 write workloads.

What host device slot and adapter does this microSDXC UHS-I card require to hit 160MB/s read?

A UHS-I microSDXC slot is required; the included SD adapter lets you use full-size SD readers that also support UHS-I speeds.

Will this A2-rated card work in my older action camera that only specifies Class 10 and U1?

Yes, the card is backward-compatible with Class 10 and U1 devices, though write speed will be limited to the host's maximum capability.
