The inventor of iDisk Tiny and the smallest USB flash drive in the world, CU-Flash, have unveiled a 4GB SD card today. Pretec Electronics Corporation’s latest creation is the SD card with the largest capacity in the world. Coming in as the king of its high speed line of 133x SD cards, the 4GB card has access speeds of up to 20MB/s, making it the fastest SD card in the world that conforms to SD 1.1 standards as well.

It is manufactured using 65 nano-meter 16Gb SLC NAND technology that makes it a notch better in terms of reliability and speed improvements of up to 500% faster than MLC NAND. Pretec’s 133X 4GB SD card is sold at $699 a pop, although current units are meant for customer sampling purposes only. Mass production is scheduled to begin by next month.

Pretec’s 2GB MMC 4.x card (MMC Plus) is available as well, and it clocks in with a 8-bit data bus and 52MHz clock rate. That makes the MMC 4.x card 400% faster than today’s SD card commonly available in the market, or 200% faster than the latest SD 1.1 specification.
