The Smaller Card with Big Storage and Fast Speeds
The miniSD was developed to meet industry demands for smaller mobile telephones, and the miniSDHC offers even more storage power and speed class options. Just like the miniSD, the miniSDHC can be used with the miniSD adapter to share a variety of digital content among devices requiring an SD card. This card was developed to meet continuing industry demands to support smaller mobile phones.
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 miniSDHC speed classes — Class 2, Class 4 and Class 6 — transfer data at least 2, 4 and 6 MB per second.
