SanDisk Ultra microSDXC Memory Card

This card is optimized for Full HD video recording with a Class 10 and U1 speed rating. While it may handle some 4K footage, it is not designed for high-bitrate 4K recording, so you may experience dropped frames or errors if used for professional-grade 4K video.

The A1 rating indicates that the card meets specific requirements for random read and write speeds, which helps apps load faster and run more smoothly when stored directly on the card. It is a great feature if you plan to expand your phone's internal storage for apps.

No, this specific package does not include an SD adapter. You will need to ensure your device has a microSD slot or that you already have a microSD-to-SD adapter if you intend to use it in a full-sized SD card slot.

Yes, it is built to withstand a wide range of temperatures, operating between -25°C and 85°C. This makes it a reliable choice for cameras or devices used in varying climates, from cold winter days to hot summer environments.

The 140MB/s is the maximum read speed under ideal testing conditions. In real-world usage, your actual transfer speeds will depend on the device you are using, the file sizes, and the quality of your card reader.
