The Register wrote Pretec released world's first 4GB SD card.
The new card provides a data access speed of 20MBps and is produced using two 65nm 16Gb SLC NAND Flash chips.
Pretec also introduced today a 2GB memory card based on the MultiMedia Card 4 specification, aka MMC Plus. Again, MMC 4-supporting devices are extremely rare, but Pretec said it was confident enough devices are currently being designed with the new spec in mind.
The 4GB SD memory card retails for $699, the price of the 2GB memory card isn't known yet.
