Bulk microSDHC for everyday devices

This pack supplies 25 SanDisk microSDHC cards, each 8 GB and rated Class 4 with UHS-I. They suit point-and-shoot cameras, game consoles, smartphones, tablets and similar devices that accept microSDHC media. The cards operate from minus 25 °C to 85 °C and are built to resist water, shock, vibration, X-rays, magnets and impact.

Adapters, cases and reader expand compatibility

Full-size SD adapters let each card work in standard SD slots, while individual plastic cases protect unused cards during storage or transport. The included USB reader provides a direct way to move files to a computer without needing a separate card slot. Together the accessories turn the raw cards into a ready-to-use kit for multiple device types.

Class 4 speed limits sustained write throughput

The Class 4 rating guarantees a minimum sustained write speed of 4 MB/s, with the manufacturer quoting up to 20 MB/s read and 5 MB/s write. That bandwidth is adequate for standard-definition video and photos, but it will bottleneck full HD or higher-bitrate recording. Devices that require faster sustained writes will not perform reliably with these cards.

Questions about this item

Will the Class 4 rating require replacement if I record full-HD video continuously?

Class 4 guarantees a minimum of 4 MB/s sustained write, so full-HD bit-rates above that level will drop frames and eventually demand a faster card.

What is the first limit reached during an all-day write session?

The 5 MB/s maximum write speed caps throughput long before the 8 GB capacity fills.

How much heat does the reader add when all 25 cards are cycled back-to-back?

Cards are rated for -25 °C to 85 °C operation; the reader draws only USB bus power and adds negligible heat.
