Pretec Introduces 8GB SDHC Card
Pretec has now released a 8GB SD card, which the company says is the highest capacity SD card in the world. The new 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 a 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 can reach the maximum capacity of 2TB (2048GB).

SDHC cards are recognized by new SDHC host devices differently than standard SD cards and are not backward compatible with legacy SD format host devices.

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