Pretec has released 8GB SD card (SDHC).

Pretec 8GB SD card is fully compliant with SD 2.0 (SDHC) specification with access speed up to 20MB/sec. The maximum capacity of SD card is 2GB under SD 1.1 of Secure Digital Alliance (SDA) specification; however, by using file format of FAT32, many SD 1.1 host devices can use 4GB SD card.

SD 1.0/1.1 uses  traditional "Byte Addressing" scheme which limits the maximum capacity to 4GB while SD 2.0 adopts "Sector Addressing" scheme which is the same with the technique applied by Mu-Card Alliance in 2004 to reach the maximum capacity of 2TB (2048GB). SDHC cards can only work with SDHC compatible host devices.

With capacities of 2GB, 4GB, and 8GB, Pretec 8GB SDHC is now available for key customer sampling at unit price $299. Mass production is scheduled by Q4/2006.
