EagleTec’s USB Nano Flash Drive has to be the smallest on the planet, at least this week. At a size of 19 x 15 x 6mm and a weight of only 3g, it can connect to a USB 1.1 or 2.0 port for automatic detection and configuring. The drive supports Windows and Mac and has a write speed of 15Mb/s. Choose between the 4GB model for $22.00 or 8GB for $33.00 and be grateful it comes with a keychain hook.
