Overview

The SanDisk 16GB Mobile MicroSDHC Class 4 Flash Memory Card is a straightforward, budget-oriented storage solution designed to add capacity to smartphones, tablets, cameras, and other devices with a microSD slot. With 16GB of space, it can hold several thousand photos, a few hours of standard-definition video, or a sizable music library — making it a practical choice for users with modest storage needs who want a trusted brand name without spending much.

The Class 4 speed rating guarantees a minimum sustained write speed of 4 MB/s, which is adequate for saving photos, transferring documents, and playing back stored media, but falls short of what is needed for recording HD video or running applications directly from the card. As microSD technology has advanced to UHS-I, UHS-II, and beyond, this card occupies the entry-level tier — reliable for basic tasks but not designed for performance-demanding workflows. It is best paired with older devices or used as simple file storage where transfer speed is not a priority.

Frequently Asked Questions

It is compatible with smartphones, tablets, cameras, and other devices that accept microSDHC cards. Check that your device supports microSDHC (up to 32GB) format before purchasing.
Class 4 guarantees a minimum sustained write speed of 4 MB/s. This is sufficient for storing photos, music, and standard-definition video, but not ideal for recording HD video or running apps directly from the card.
The product listing does not confirm inclusion of an SD adapter. If you need to use it in a full-size SD slot, verify adapter inclusion or purchase one separately.
Class 4 speed is generally too slow for reliable continuous HD video recording. For HD or 4K video, a Class 10 or UHS-rated card is recommended.
