SanDisk microSDHC 16GB Class 4 card

This SanDisk microSDHC card provides 16GB of storage for devices that accept the microSD form factor. It is suited for basic recording tasks in cameras, dash cams or older smartphones where high write speeds are not required. The Class 4 rating guarantees a minimum sustained write speed of 4 MB/s. No adapter is included in the package.

Sustained write performance at Class 4

The Class 4 rating means the card maintains at least 4 MB/s during continuous writing, which is adequate for standard-definition video or intermittent photo bursts. Under sustained load the throughput will not exceed this class floor by a significant margin. It is not designed for prolonged high-bitrate recording or rapid sequential shooting. Performance remains consistent within the Class 4 specification.

Upgrade considerations and limitations

This card replaces lower-capacity microSD or microSDHC cards where 16GB provides more room for media files. The jump is worthwhile when a device is limited to the microSDHC standard and cannot use larger SDXC cards. It does not suit applications needing UHS-I speeds, 4K video capture or frequent large file transfers. Buyers who need faster sustained writes should look for a higher speed class.

Questions about this item

Will this Class 4 card overheat during all-day video recording?

The card is rated Class 4 with no published thermal throttling data; microSDHC cards of this class typically run cool in normal use.

What device slot is required for this 16GB microSDHC card?

A microSDHC or microSDXC slot is needed; the card will not fit full-size SD or miniSD slots without an adapter.

Will this Class 4 microSDHC work in a device that only supports standard microSD?

Standard microSD slots do not support the SDHC protocol, so the 16GB capacity will not be recognised in those devices.
