microSDHCThe Smallest Card That Does Even MoreThe microSDHC cards are ideal for storing media-rich files such as music, videos, and high-resolution images. In fact, the microSDHC cards offer even greater storage (above 2GB) for the mobile world's wide array of capacity needs while remaining the standard microSD card's physical size.
High-Capacity StorageThe microSDHC cards are ideal for storing media-rich files such as music, videos, and high-resolution images, just like the miniSD and SD cards. In fact, microSDHC cards offer even more storage (from 4 to 32GB) for the mobile world's wide array of capacity needs. The microSDHC card delivers all of these benefits in a tiny package, making it ideal for mobile products.
Wide Market AdoptionThe microSD and microSDHC are the leading memory card standards adopted by mobile handset vendors because of its ultra-compact size and widely supported standard SDHC interface.
Although primarily used with mobile handsets, the microSDHC card also is supported natively in a variety of hand-held GPS devices, portable audio players, video game consoles and expandable USB flash memory drives. Compatibility and InteroperabilitymicroSDHC cards are backward compatible with electronic devices that are SD enabled. By using an appropriate adapter, the microSDHC card can easily and quickly be inserted into any device that supports a SDHC or miniSDHC card. |
The SD Association has established a new specification rating for the minimum data transfer for standard and high-capacity cards as well as both types of host products. With the new Speed Class specifications, the host product can check the fragmented state in the card and calculate the write speed in each part of the card. The host can then determine where to write the data according to its speed requirement.The three microSDHC speed classes — Class 2, Class 4 and Class 6 — transfer data at least 2, 4 and 6 MB per second.
