The Samsung T7 microSDXC card is a 512GB UHS-I card rated for up to 170 MB/s read and 170 MB/s write, with V30 video class and A2 app performance. The 170 MB/s write rating is the standout: most UHS-I cards in this class write far slower, so offloading footage and installing apps is quicker. It suits action cameras, drones, phones and the Steam Deck or Switch, where sustained write speed matters more than peak read. Against SanDisk Extreme and Lexar 1066x cards it trades a little peak read speed for stronger write performance and Samsung's six-proof protection.

Owners rate the T7 card highly for real-world write speed and reliability in cameras, drones and handhelds. Reviewers note it is one of the fastest UHS-I microSD cards and holds up over long recording sessions, though some wish it were UHS-II.
