The Toshiba TransMemory U364 64GB is an ultra-compact usb stick for on the go. Because of the thin size you leave the stick in your laptop while you carry it in your laptop cover. Or you put it in the USB port of your car radio without being in the way. Moreover, the stick only weighs 3 grams, which is about as light as a small pack of chewing gum. The writing speed of the usb stick is 60MB / s higher than most small usb sticks. So you write a HD video of 1GB in less than 10 seconds.
