Datasheet

Starting at 4GB, miniSDHC cards offer higher storage capacity for high-resolution multimedia content and support more demanding data transfer rates. Kingstons miniSDHC cards use new speed class ratings known as Class 4 and 6 that guarantee a minimum data transfer rate for optimum performance with devices that use miniSDHC storage devices.

Although identical in size to todays standard miniSD card, the new miniSDHC cards are designed differently and are only recognized by miniSDHC host devices. When used with the included adapter, they can be used as full-size SDHC cards. To ensure compatibility, look for the miniSDHC or SDHC logo on cards and host devices (e.g., cameras and camcorders).

For added reliability and durability, Kingston solidstate miniSDHC memory cards are built of nonvolatile memory components and have no moving parts that could wear out or break. All cards are 100-percent tested and are backed by a lifetime warranty and free live technical support.
