The drive will come in orange, red, blue, clear, and gray colors, retailing for $24. Most of us are used to the sight of a small dongle hanging out of notebooks and computers, functioning as USB flash drives, but the diminutive number you see here from TopTechProducts was fashioned after a credit card (although you can’t swipe it), letting you carry it around in your wallet at all times. 1″ x 0. Too bad storage capacity maxes out at 4GB, although that should be considered more than enough for most users. It measures 3. The card itself can fold in half, and comes with a tiny USB connector that plugs into the computer. 11″ and works with Windows, Linux and Mac computers. 4″ x 2. 99 each.
