diskgoYou can never be too rich, too thin, or — in the world of USB flash drives, at least — have too much capacity. That seems to be the mantra behind the latest high-capacity thumbdrives, which are pushing the limit at 8GB. The latest, Edge's 8GB DiskGO, matches last month's JetFlash in capacity, weighs in at half an ounce, and undercuts the JetDrive with a price of around $600, compared to the JetFlash's $675. Of course, for just $530, you can pick up two of Edge's 4GB drives, but why would you do that when you can dump everything into one 8GB drive and lose all your data at once when you misplace it?
