Stop waiting for your gear to keep up. The SanDisk 128GB Extreme SDXC UHS-I Memory Card is engineered for creators who demand speed, reliability, and performance in every shot. Powered by SanDisk QuickFlow Technology, this card delivers card offload read speeds of up to 180MB/s — pushing well beyond the standard UHS-I 104MB/s ceiling when paired with compatible devices. For peak transfer performance, pair it with the SanDisk Professional PRO-READER SD and microSD (sold separately).
Built for 4K Creators and Burst Shooters
Whether you're filming cinematic 4K UHD footage or hammering the shutter in sequential burst mode, this card handles the load. Write speeds up to 90MB/s mean your camera buffer clears fast and stays ready. With UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings, sustained video capture runs at a minimum of 30MB/s — keeping your recordings smooth and stutter-free, frame after frame.
Confidence in Every Condition
Rated Class 10 (C10) and fully compliant with 4K UHD recording standards, the SanDisk Extreme SDXC is a dependable workhorse for mirrorless cameras, DSLRs, and advanced action cameras alike. Performance may vary depending on host device, interface, and usage conditions. 1MB = 1,000,000 bytes; actual user storage is less than stated capacity.
