1TB microSDXC card for 4K capture

This SanDisk Extreme microSDXC card delivers 1TB of storage for devices that use the UHS-I interface. It carries Class 10, U3, V30 and A2 ratings, making it suitable for 4K UHD and Full HD video recording as well as faster app loading on compatible smartphones, drones and action cameras. The bundled SD adapter lets you use the card in full-size SD slots.

Thermals and power in typical use

As a solid-state memory card it has no moving parts and draws minimal power from the host device during read or write operations. Heat output stays low enough that no active cooling is required, and the card runs silently in normal photography or video workflows.

Adapter and software extras

The included SD adapter provides mechanical compatibility with standard SD card readers and camera slots. SanDisk Memory Zone app support simplifies file management on Android devices, while the one-year RescuePRO Deluxe download offer adds a recovery option for accidentally deleted photos or videos.

Questions about this item

How do I install the microSDXC card and SD adapter so the host device recognises the full 1TB capacity?

Insert the microSD card into the included adapter with the gold contacts facing down, then seat the adapter firmly in the SD slot; the host must support the SDXC standard to address the 1TB capacity.

Will the card need reformatting or wear-level maintenance after heavy 4K UHD recording?

The card handles wear-leveling internally; no user maintenance is required, though occasional reformatting in the camera keeps the file system clean for sustained V30 video capture.

At what point does sustained write speed hit the V30 floor during long 4K clips?

The V30 rating guarantees a minimum 30MB/s sequential write, so the 90MB/s peak will throttle to that floor once the buffer fills during extended recording.
