Flash Card Speeds to Triple by 2012
New standards for flash memory cards are being developed by the SD Card Association which will increase data transfer by close to 300%. The specs should be complete early 2011 and be in production early 2012.
Today's SD cards have data-transfer buses with a maximum speed of 104MB per second, though actual read and write speeds are somewhat slower. The new specification, just called SD 4.0 for now, will increase that to 300MB/sec, said Kevin Schader, the association's director of communications. The SD speeds are increased through the addition of a second row of electrical contacts on the bottom face of the card, though the association is still debating just how many new pins to add, Schader said
