Samsung PRO Ultimate 256GB UHS-I microSDXC Card with SD Adapter

The Samsung MB-MY256SA/AM is a PRO Ultimate 256GB microSDXC card designed for users who need quick transfers, reliable 4K video capture, and extra room for large mobile apps. Built on the UHS-I interface, it reaches up to 200 MB/s when reading files and up to 130 MB/s when writing, so footage moves to a computer or phone in less time and burst photos save without delay.

This card fits naturally into action cameras, drones, Android phones, and tablets where smooth 4K recording or fast in-game loading matters. The A2 rating allows an Android device to open and switch between demanding apps with less waiting, which is useful for power users, mobile gamers, and on-the-go content creators who edit clips directly on their phone.

Samsung protects the card against water, X-rays, drops, wear, magnets, and temperatures from -13 to 185°F, giving photographers and travelers confidence when shooting on the beach, at a ski slope, or during a long haul flight. Whether recording a family vacation or backing up drone footage in a remote location, the card keeps data safe.

An included full-size SD adapter lets you move the card between a mirrorless camera, laptop reader, or printer without hunting for extra gear. One card serves multiple devices, making workflow simpler for anyone who juggles cameras, phones, and tablets.
