A unknown company called PQI Taiwan has launched the world’s thinnest flash drive, it is 3mm thick and is no bigger than a credit card. You may have seen something similar to this with a capacity of 512MB or 1GB, but this one holds a massive 16GB of data. It connects to a computer using USB 2.0 and is compatible with both Mac and Windows computers. It has a built in retractable cord to maintain the slim design. The U510 will be available in silver, iron gray and a special edition World Cup laser etched version.
