For those who have always wondered about the amount of space they have left in their USB flash drives, they’ll have to plug it in a computer to check the results. The Corsair Readout USB 2.0 Flash Drive is different since it already comes with a built-in display that shows the capacity used, available space, and even a personal ID. This Bi-stable Cholesteric Display (BCD) can retain and display this information for up to one year without the need for a battery, although what happens after one year, I’m not too sure. You can even enter a personalized 11-character alphanumeric label to help you identify the contents better. Each purchase of the 4GB Corsair Readout USB 2.0 Flash Drive will set you back by $76.
