Overview

The SanDisk 128GB Ultra microSDXC card is designed for everyday storage needs in action cameras, smartphones, and tablets. With read speeds up to 100MB/s, it handles file transfers efficiently, and its UHS Speed Class U1 and Speed Class 10 ratings ensure smooth Full HD (1080p) video recording and playback. The A1 app performance rating makes it a practical choice for Android devices that use the card as adoptable storage, enabling faster app loading and operation compared to cards without the A1 designation.

Durability is a notable strength of this card. SanDisk rates it shockproof, temperature-proof, waterproof, and X-ray-proof, so it can withstand the rough handling that comes with action camera use. The bundle includes an Everything But Stromboli micro card reader, providing a ready-made solution for transferring files to a computer without needing a built-in card slot. With 128GB of capacity, the card holds a significant amount of Full HD footage — making it a practical companion for the GoPro Hero 4 and Hero Session cameras it is specifically marketed for.
