SanDisk SDSQXBZ-256G-ANCMA Extreme Plus 256GB microSDXC Card

The SanDisk Extreme Plus 256GB microSDXC card is built for users who need reliable, high-speed storage in compact devices. With sequential read speeds up to 170MB/s and write speeds up to 90MB/s, it handles the demands of 4K UHD video recording, rapid burst photography, and large file transfers with ease. The V30 and U3 speed class ratings guarantee a minimum 30MB/s sustained write speed — the baseline for smooth 4K capture — making it a dependable choice for action cameras, drones, and mirrorless cameras that accept microSD media. The A2 Application Performance Class rating goes further by optimizing random read and write operations, which translates to faster app loading and smoother performance when running applications directly from the card on Android smartphones and tablets.

At 256GB, the card provides ample room for hours of 4K footage, thousands of high-resolution images, or a substantial library of apps and media. SanDisk's Extreme Plus line is designed with durability in mind, offering resistance to water, shock, temperature extremes, and X-rays. The included full-size SD adapter extends compatibility to laptops, DSLR cameras, and desktop card readers, making it easy to offload files without additional accessories. For anyone working with demanding media formats across multiple devices, this card strikes a strong balance between capacity, speed, and versatility.
