Overview

The SanDisk Extreme Plus 128GB microSDXC card is designed for users who need reliable high-speed storage in a compact form factor. With a UHS-I interface delivering up to 95MB/s sequential read speeds, it handles the demands of 4K Ultra HD video recording and rapid burst-mode photography. The U3 and V30 speed class ratings guarantee a sustained minimum write speed of 30MB/s, which prevents the buffering issues and dropped frames that can plague slower cards during continuous recording.

At 128GB, the card provides enough room for hours of 4K footage or thousands of high-resolution photos, making it well suited for action cameras, drones, and smartphones. The included full-size SD adapter extends its usefulness to DSLR cameras, camcorders, and laptops equipped with standard SD card slots. While this card uses the older UHS-I bus rather than the faster UHS-II standard, its speed is more than sufficient for the recording and playback needs of most consumer devices that accept microSD cards.
