What this card is and who it suits

The SanDisk Ultra SDXC UHS-I card delivers 128GB of storage for compact and mid-range point-and-shoot cameras or camcorders. It supports Full HD video recording and Class 10 U1 speed ratings for reliable capture. Photographers who need up to 256GB of total capacity across cards will find the space practical. It is not for buyers who want more storage on a single card or who require higher sustained write speeds for professional workflows.

What to check before ordering

Confirm that your camera or camcorder accepts full-size SDXC cards and supports the UHS-I interface. The card reads at up to 120MB/s, so verify your card reader or computer port can utilise that speed for faster offloads. Ensure the device firmware recognises 128GB capacities. It is not for builders who need a second card slot filled with a different form factor or who rely on faster bus standards not present in their gear.

Build quality and daily use

The card is water-proof, temperature proof, X-ray proof and shock proof for durability in varied shooting conditions. A supplied lanyard helps keep the card secure during transport or on location. Standard SD dimensions mean it fits any compatible slot without adapters. It is not for users who need ruggedised metal housings or integrated write-protect switches beyond the standard SD tab.
