SanDisk 16GB microSDHC Class 4 Kit 250 Cards + Reader

Bulk kit for volume deployments

This kit supplies 250 SanDisk 16GB microSDHC cards and a USB reader in one package. Each card is rated Class 4 for a minimum sustained write speed of 4MB/s. The bundle suits organisations that need large quantities of identical removable media for fleet roll-outs, kiosks or educational sets. Individual plastic cases protect every card during distribution and storage.

Class 4 write profile under sustained load

Class 4 guarantees a minimum sequential write of at least 4MB/s across the full 16GB capacity. The rating reflects steady-state throughput rather than a brief burst, so extended recordings or batch copies maintain that floor. Cards conform to the microSDHC specification covering 4GB to 32GB capacities. Older hosts that pre-date the SDHC standard may not recognise these cards.

Silent solid-state operation with minimal draw

Flash memory has no moving parts, so the cards run silently and draw very little power from the host device. Heat output is negligible during typical read and write cycles. The included USB reader adds a single standard interface for desktop or laptop access without external power.
