SanDisk Extreme Pro 128GB SDXC UHS-I U3 V30 Class 10 Memory Card (SDSDXXY-128G-GN4IN)

128 GB SDXC UHS-I card

The SanDisk Extreme Pro 128GB SDXC card delivers read speeds up to 170MB/s and write speeds up to 90MB/s. It carries UHS Speed Class 3 (U3), Video Speed Class 30 (V30) and Class 10 ratings for sustained performance. The card is built for 4K UHD video capture and sequential burst-mode photography. Photographers and videographers who need reliable high-speed storage will find it suited to demanding workflows.

Temperature proof waterproof shockproof x-ray proof

The card is tested to withstand extreme temperatures, water immersion, physical shock and airport x-ray scanners. Its SDXC form factor fits standard SD slots in cameras, drones, laptops and card readers without adapters. Daily handling in harsh environments or frequent travel poses minimal risk to stored data. Creators working outdoors or in unpredictable conditions gain confidence that the media survives the journey.

Upgrade from slower Class 10 or U1 cards

Moving from a basic Class 10 or UHS Speed Class 1 card removes bottlenecks during 4K recording and long burst sequences. The jump is worth it when sustained write speeds above 30MB/s are required to prevent dropped frames or buffer delays. Users shooting Full HD only or transferring occasional photos will not see a practical benefit. The 128GB capacity also limits extended 4K sessions without offloading.
