SanDisk 25 x 16GB microSDHC Class 4 SDSDQM-016G with Cases

Bulk microSDHC kit for high-volume needs

This kit supplies twenty-five SanDisk microSDHC cards, each offering 16GB of storage. The Class 4 rating guarantees a minimum write speed of 4MB/s for general-purpose recording. Supplied protective cases keep every card organised and shielded during transport or storage. Ideal for schools, drone fleets or security installations that need many identical cards ready to deploy.

Standard microSD form factor with included cases

Each card uses the microSDHC format, fitting directly into phones, action cameras, dash cams and handheld consoles that accept the smaller slot. The bundled cases provide individual slots so cards stay labelled and dust-free between uses. Adapters let the same cards work in full-size SD, miniSD, Memory Stick or USB readers when required. No moving parts and solid-state construction mean reliable operation in vibrating or temperature-variable environments.

Step up from 2GB microSD or lower-class cards

The 16GB capacity replaces original microSD cards limited to 2GB, giving eight times the space for photos, video or data logs. Class 4 write performance suits standard-definition recording and everyday file transfers without the cost of faster classes. Buyers who need 4K capture, burst photography or sustained high-bitrate streams should look at Class 10 or UHS-rated media instead. Older hardware built before the microSDHC specification may not recognise these larger capacities.
