Overview

The SanDisk Ultra 64GB SDXC UHS-I Memory Card (SDSDUN4-064G-GN6IN) is a straightforward, reliable storage solution designed primarily for compact and mid-range point-and-shoot cameras. With read speeds up to 120MB/s — achieved through SanDisk's proprietary technology that pushes beyond the standard UHS-I 104MB/s ceiling — transferring a day's worth of photos and video clips to your computer is fast and efficient. The 64GB capacity strikes a practical balance between having enough space for extended outings and keeping the price accessible.

Rated at UHS Speed Class 1 (U1) and Class 10, the card delivers the sustained write performance needed for smooth Full HD 1080p video capture without dropped frames or buffer issues. Its physical durability is another strong point: SanDisk has engineered it to be water-proof, X-ray-proof, and temperature-proof, so it can withstand the kind of conditions that outdoor and travel photographers routinely encounter. While this particular model has been discontinued, it continues to be available through existing stock and remains a proven choice for anyone who needs dependable storage for Full HD shooting without paying a premium for features like U3 or V30 ratings they may not need.
