SanDisk 16GB microSDHC Class 4 3-pack memory card

Everyday Storage for Mobile Devices

This three-pack supplies 16 GB microSDHC cards rated Class 4 for standard-definition capture and file transfer. Each card works with phones, tablets, point-and-shoot cameras and game consoles that accept the microSDHC format. The bundle includes SD adapters and a single reader so the cards can also be used in full-size SD slots. Buyers who need faster write speeds for high-bitrate video or burst photography should look elsewhere.

Rugged Build with Adapter Flexibility

SanDisk rates the cards as water proof, shock proof, vibration proof, X-ray proof, magnet proof and impact proof, with an operating range from -25 °C to 85 °C. The bundled plastic cases protect individual cards during transport and storage. The supplied SD adapters let you move the same media between microSD and standard SD devices without extra purchases. The single reader covers both formats but only one card can be accessed at a time.

Class 4 Speed Ceiling

Sequential read reaches up to 20 MB/s and write up to 5 MB/s, which matches the Class 4 minimum sustained write specification. This throughput suits standard-definition video recording and basic photo storage but will bottleneck 4K capture or rapid sequential shooting. The UHS-I interface is present but performance remains bound by the Class 4 rating. Users requiring higher sustained write rates need cards with a faster speed class.
