Pretec has today announced the highest capacity SD card to date, their new 8 GB SD-HC. This new card is twice the capacity of cards announced by Panasonic, Toshiba and SanDisk and means that SD cards will soon be available in capacities as high as the largest CompactFlash cards. Pretec's press release doesn't reveal very many details other than compliance with the SD-HC specification (which has a maximum throughput of up to 20 MB/sec; we expect the throughput of this card to be significantly lower). The Pretec 8 GB SD-HC card has a 'sampling price' of $299 and should be in mass production in the last quarter of this year.

Press Release:

Pretec 8GB SDHC card, the highest capacity SD card in the world!

Fremont, California, August 31st, 2006 ? Pretec, the world record keeper of highest capacity flash memory cards of CF card (12GB, March 2004), USB Flash Drive (8GB, January 2005), SD card (4GB, July 2005) and MMC (4GB, September 2005), has now released 8GB SD card, the highest capacity SD card in the world.

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 which Pretec pioneered since 2005. 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). Pretec is one of the major founders and main contribution member of Mu-Card Alliance, who joined force with MMCA in June 2005 ( 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.

SDHC cards are recongnized by new SDHC host devices differently than standard SD cards and are not backward compatible with legacy SD format host devices; in which, SDHC cards can only work with SDHC compatible host devices. Since Pretec is the 1st in the world to offer 4GB standard SD cards, and now also offers 4GB SDHC cards, Pretec will provide patent-pending SD-Tuner™ technology for customers to have an easy transition between the incompatibility of SD 1.1 and SD 2.0.
