SanDisk 8GB microSDHC Class 4 UHS-I 5-pack with adapters and reader

Five-pack microSDHC cards for everyday capture

This set supplies five 8GB SanDisk microSDHC cards rated Class 4, each bundled with its own full-size SD adapter. The pack also includes a single USB reader so the cards can be used straight away with laptops or desktops. They suit photographers, tablet owners and console users who want ready-to-go storage for photos and standard-definition video.

Class 4 rating sets the write baseline

The cards carry a Class 4 speed rating, which guarantees a minimum sustained write speed of 4 MB/s. SanDisk quotes peak read speeds up to 20 MB/s and write speeds up to 5 MB/s, so the Class 4 figure is the only number that tells you whether the card meets a device’s minimum requirement. Buyers needing faster sustained writes for high-bitrate recording should look for a higher class.

Built to survive tough environments

SanDisk states the cards operate from -25 °C to 85 °C and are tested water proof, shock proof, vibration proof, X-ray proof, magnet proof and impact proof. That durability lets them handle daily transport in pockets, bags or outdoor gear without data loss. The reader adds convenient offload, but the cards themselves are the rugged component.
