Designed for action cameras and mobile devices, the 32GB Extreme UHS-I microSDHC Memory Card from SanDisk features a storage capacity of 32GB and supports maximum read speeds of 100 MB/s and maximum write speeds of 60 MB/s. This card has also been designed with the V30 Video Speed Class rating, which guarantees minimum write speeds of at least 30 MB/s. All of this allows for users to immerse themselves in extreme sports videography and photography at resolutions of Ultra HD 4K (3840 x 2160) and Full HD (1920 x 1080).

While this card has been designed for cameras that are UHS-I / V30 compatible, it may be used in devices that do not support UHS-I / V30. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U3, which also supports minimum write speeds of 30 MB/s, UHS-I and U1, which supports minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.

Aside from support for UHS-I, V30, and U3, SanDisk also built this card with support for the Application Performance Class 1 (A1) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A1 spec allows the card to manage random read input-output access per second (IOPS) operations so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles, and in-app permissions.

As with most SanDisk media, this memory card is shockproof, X-ray proof, and waterproof, while also being able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow, deserts, and pools. Should the card's data become compromised, you also benefit from the option to download RescuePRO Deluxe software as well as a limited lifetime warranty. Included is a microSD to SD adapter, allowing this card to be used in SD-compatible devices.
