Kingston's microSDHC Class 4 cards offer higher storage capacity &
performance that meets the Class 4 Standard. Kingston's microSDHC cards use the
new speed 'class' rating that guarantee a minimum data transfer rate for optimum
performance with devices that use microSDHC. Identical in physical size to
today's standard microSD card, the microSDHC cards are designed to comply with
SD Specification Version 2.00 and are only recognized by microSDHC host devices.
They can be used as full-size SDHC cards when used with the included adapter.
To ensure compatibility, look for the microSDHC or SDHC logo on host devices
(e.g. phones, PDAs, and cameras).
