Overview
Not a high end camera card, this SanDisk Ultra is tested to work with Chromebooks, adding storage for files, photos and Android apps. An adapter lets it slot into full size SD readers.
Chromebook certification and app speed class make it a simple storage boost for laptops and tablets. Its speed class targets Full HD, so ultra HD cameras need a faster card.
Who it's for
Students and Chromebook owners short on space will find it an easy upgrade. Drone and action camera users should choose a higher speed class card.
Pros and cons

Read speed above the standard bus limit needs a compatible device; otherwise it runs at normal UHS-I rates. The app performance class sets minimum random speeds for loading apps from the card. Its base sustained write class suits Full HD video.
