Buying Guide

Match capacity to your use case

Choose 64–128GB for media-heavy use, 200–512GB for large video libraries or offline maps, and higher if you routinely record high-bitrate 4K video

Check speed class and A1/A2 ratings

U3 and A1/A2 ratings indicate sustained write and app-performance suitability—important for recording video and running apps from the card

Prefer cards with adapters or readers

Included SD adapters or USB readers simplify moving files between tablets and computers without buying extra accessories

Consider real-world transfer speeds

Look for manufacturer claims and independent tests for read/write throughput; higher sustained write speed reduces dropped frames during video capture

Balance brand reliability and warranty

Established brands with explicit warranties and good user ratings reduce the risk of data loss—factor that into value comparisons
