Description

The SanDisk Extreme Pro microSD Card 256GB is a microSDXC memory card with a formatted capacity of 256 GB. It is built to meet the demanding requirements of modern high-performance devices. It is rated UHS-I (U3) and Video Speed Class 30 (V30), which guarantees a minimum sustained write speed of 30 MB/s. This is a critical feature for ensuring smooth, uninterrupted 4K video recording and high-speed burst photography without dropping frames.

The card is also rated A2 for app performance. This means it provides faster random read and write speeds, which can significantly improve the performance of mobile applications, making it an excellent choice for expanding the storage of an Android smartphone. The drive leverages SanDisk QuickFlow Technology to achieve impressive sequential read speeds of up to 200 MB/s and sequential write speeds up to 140 MB/s. For optimal performance, especially the maximum read speed, the card should be paired with a compatible card reader, such as the SanDisk Professional PRO-READER. As with other SanDisk Extreme products, this card is built for durability and is waterproof, temperature-proof, shockproof, and X-ray proof, making it a reliable choice for use in extreme environments. It comes with an SD adapter for compatibility with full-size SD card slots and is backed by a limited lifetime warranty.
