SanDisk microSDHC 16GB Class 4 25-pack

Bulk microSDHC for volume deployments

This kit contains twenty-five SanDisk microSDHC cards, each offering 16GB of removable storage. The Class 4 rating guarantees a minimum sustained write speed of 4MB/s for general-purpose recording. Cards use the microSDHC format, which spans capacities from 4GB to 32GB and requires a compatible host device. The multi-pack suits organisations, schools or installers needing many identical units at once.

Replacing single retail cards or smaller capacities

Buyers currently opening individual retail packs save handling time by receiving twenty-five cards in one package. The jump from 2GB legacy microSD cards adds usable space while keeping the same physical footprint. Devices manufactured before the SDHC specification will not recognise these cards, so older hardware must be checked first. The upgrade is worthwhile when a fleet of devices all support the microSDHC standard.

Steady write throughput for continuous logging

Class 4 performance delivers at least 4MB/s during long captures such as dash-cam loops or time-lapse sequences. Sustained write speed stays consistent because the card has no moving parts and uses permanent solid-state storage. Burst transfers may run faster, but the class rating defines the floor that matters for uninterrupted recording. Heat and vibration resistance suit fixed installations in vehicles or outdoor enclosures.
