Panasonic, the brand for which Matsushita Electric Industrial Co. Ltd is best known, announced that it is developing a 4GByte SD High-Capacity (SDHC) memory card based on the new SD Specifications Version 2.00. The new specifications were established to meet the demand for high definition (HD) video and high-resolution image recording used in many SD-enabled devices. The memory card is scheduled for release in the summer of 2006.

According to the press release, the demand for higher-capacity SD memory cards still continues to grow due to the widespread use of high-resolution digital cameras and semiconductor audio and video players. Reacting to growth in the market for such devices, the SD Card Association released SD Specifications Version 2.00 for the capacity beyond 2GBytes.

With the new specifications, it became possible to develop SDHC memory cards with capacities up to 32GBytes. In addition, Version 2.00 specified to guarantee the minimum sustained data transfer speeds by establishing card performance classes for recording the streaming MPEG data. The previous versions of the specification did not provide such common standards for sustained data transfer speeds to be shared by all manufacturers. The new approach allows users to select card performance based on the needs of particular applications such as HD video and other MPEG applications with high data storage capacities.
