Right when you think you've got a cable standard down that works with most of your devices, some committee or commission of some sort goes and releases a new, better standard to upgrade to. It's pretty annoying, but it's one of the things you've got to deal with in technology. It moves pretty fast, after all. So first there was USB, then there was USB 2.0, and now, wouldn't you know it, we're about to get USB 3.0.
USB 3.0 improves upon its successors by adding fiber-optic cable alongside the copper wiring, greatly increasing the speeds. The upgrade should allow for high-def devices, such as HD DVD or Blu-ray players, to use the standard to send data. As of now, today's USB cables aren't fast enough for such heavy transfers, sending data at 480 megabits per second. USB 3.0, on the other hand, will increase that tenfold to a whopping 4.8 gigabits per second. The fancy new cables should start hitting shelves and being used in devices around 2009 or 2010.
