SanDisk, the 500-lb. gorilla of the memory card market, says it will release a 4 GB SDHC card before the end of July.
Although standard SD and SDHC cards look identical in size and shape, only SDHC-compatible products will be able to accept cards using the new format.
When available, SanDisk’s 4 GB SDHC card will cost $200 or 160 Euros.
More information on this card is available on the SanDisk web site.
Panasonic has also announced it will introduce a 4 GB SDHC card, but this won’t happen until next month, and the price for this has not yet been revealed.
Why a New Format?
The primary goal of the new SDHC Memory Card format is to expand SD card capacity beyond 2 GB.
Although there are already 4 GB SD cards on the market, in order to reach these capacities they have to be formatted with FAT32, which is not part of the SD specification. Therefore many consumer electronic devices can not read these cards, as they support only FAT16.
The SDHC format supports cards up to 32 GB in capacity.
The new SDHC specification will also guarantee a minimum SD Speed Class Rating, which for video products is equivalent to MPEG-2 video.
This new format will eventually completely replace the SD format.
