4 GB SDHC Memory Card from Panasonic
Panasonic today announced that it is developing a 4 GB SDHC (SD High-Capacity) Memory Card based on the new SD Specifications Version 2. The new specifications were established to meet the growing demand for High Definition video and high-resolution image recording used in many SD enabled devices. The 4 GB SDHC Memory Card is scheduled for global release in the summer of 2006.
SD Spec v2
Since its introduction in the year 2000, the SD Memory Card has been accepted by a wide range of digital devices, backed by its four main advantages - compact size, high data storage capacity, fast data transfer speed and advanced copyright protection features. 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 remarkable growth in the market for such devices, the SD Card Association released SD Specifications Version 2.00 for the capacity beyond 2 GB.
With the new specifications, it is now possible to develop FAT 32 based SDHC Memory Card with capacities up to 32 GB. In addition, the new Specifications Version 2.00 specified to guarantee the minimum sustained data transfer speeds by establishing card performance classes (Class 2: 2 MB/s; Class 4: 4 MB/s; Class 6: 6 MB/s) for recording the streaming MPEG data. The previous versions of the specification did not provide common standards for sustained data transfer speeds.
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. The new specifications continue to offer copyright protection features, making it an ideal solution for digital content distribution.
