Capacity and target use

This SanDisk Extreme Go SDXC card provides 128GB of storage for photographers and videographers who need reliable capture of high-resolution images and 4K UHD footage. The UHS-I U3 V30 rating supports sustained write performance for continuous recording without dropped frames.

Build quality and daily handling

NAND flash technology underpins the card's durability while the housing is temperature proof, waterproof, shock proof and magnet proof. These protections mean the card survives airport scanners, sudden drops, immersion and extreme climates without data loss.

Thermals, noise and power draw

Solid-state construction eliminates moving parts, so the card runs silently and generates negligible heat during read or write operations. Power draw is minimal, allowing extended shooting sessions on camera batteries without noticeable impact on runtime.

Questions about this item

What does the UHS-I U3 V30 rating mean for real-world 4K video?

The U3 and V30 marks guarantee a minimum sustained write speed of 30 MB/s, which meets the bitrate demands of most 4K UHD cameras.

Will this 128 GB SDXC card fit my camera's standard SD slot?

Yes, it uses the standard SDXC form factor, so it fits any device with a full-size SD card slot that supports SDXC capacity.

How do I get the advertised 230 MB/s read speed when offloading footage?

Use a UHS-I card reader connected to a USB 3.0 or faster port; the card will not reach that rate over USB 2.0 or built-in laptop readers limited to lower speeds.
