Designed for computers, smartphones, tablets, drones, DSLRs, sports/action cameras, and more, the 256GB UHS-I microSDXC Memory Card from Hyundai features a storage capacity of 256GB and supports maximum read speeds of 100 MB/s and maximum write speeds of 90 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 photography and videography 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 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.

To help ensure greater durability, this card is able to withstand temperatures ranging from -13 to 185°F, allowing you to take this card into extreme environments. Included is a microSD to SD adapter, allowing this card to be used in SD-compatible devices.
