The SanDisk 128GB Extreme UHS-I microSDXC Memory Card is engineered for microSD-compatible devices like smartphones, drones, and action cameras that record Full HD and 4K video, along with raw and burst mode photography. It offers a 128GB capacity and supports the UHS-I interface. Rated V30, it ensures minimum sustained write speeds of 30 MB/s. For devices without V30 compatibility, it also meets the U3 standard, maintaining the same minimum write speed. The card delivers read speeds up to 190 MB/s and maximum write speeds of 90 MB/s. In addition to UHS-I, V30, and U3 support, this SanDisk card is designed to meet the Application Performance Class 2 (A2) standard, enhancing mobile performance for Android users. The A2 specification optimizes random read IOPS, enabling faster app launches and efficient handling of related tasks like audio, graphics, saved profiles, and in-app permissions, resulting in a smoother mobile experience. This SanDisk memory card is built to endure harsh conditions, featuring shockproof, x-ray proof, and waterproof protection, and operating reliably in temperatures from -13 to 185°F. It includes access to RescuePRO Deluxe software for data recovery and the Memory Zone app for easy file management and backup on Android devices. A microSD to SD adapter with a write-protect switch is also provided, enabling compatibility with SD card slots while safeguarding your data.
