SanDisk has begun sampling 6 and 8-gigabyte (GB) microSD High Capacity (microSDHC) flash memory cards to major phone manufacturers and mobile network operators (MNOs) for testing and evaluation. The new cards are ideal for the growing number of feature-rich multimedia handsets that bring together phones, music players, hand-held computers, digital cameras and more.

SDHC is the designation for any SD or SD-based card that is larger than 2GB and adheres to the new SD 2.00 specification required for cards and hosts to support 4GB to 32GB capacities. The specification was developed by the SD Association, an industry standards board, which has also created three classes to define minimum sustained data transfer speed. These cards adhere to the SD Speed Class 4 Rating.3

Retail release of the cards and availability to phone manufacturers and network operators are planned for later in 2007. Pricing has not yet been determined.
