Information technology seems as if we've been writing about USB three.0 forever, but it has really been only most two years since Intel and other parties formed a promotional group for USB three.0 in 2007. The spec was completed in Nov 2008, at which time the standard's backers said that a glut of devices would hit the market tardily this year. Well, that statement turned out to be almost right: Devices are coming very before long, but the glut won't be until next year.
SuperSpeed USB (as USB 3.0 is called) supports a maximum data rate of 4.8 gigabits per second, compared with 480 megabits per 2d for Hi-Speed USB (USB 2.0). That amounts to a theoretical maximum of 600 megabytes per second–information technology'due south way faster than almost hard drives, and it's coming only in fourth dimension for a wave of newer and speedier solid-state drives. To give you an idea of how fast that is, it's the equivalent of moving most ane full CD'due south worth of data in ane 2nd.
USB iii.0 achieves those speeds with a new plug and cable format, but it'south all astern-compatible with USB 2.0 and USB 1.1. Plug in your one-time device, and it will nevertheless piece of work (at the older speed). Plug a USB 3.0 device into a USB 2.0 port, and information technology will run at the slower speed.
What's more than, the USB three.0 protocol is at present full-duplex: Devices can send and think information simultaneously, which wasn't true with USB ane.i and 2.0. Lower operating voltages and the elimination of dissemination and polling (methods that the previous USB standards used to communicate with all attached devices) should make USB hosts draw less ability, but a higher maximum carried voltage should aid you charge your portable devices more chop-chop.
It sounds groovy–and recently information technology seemed poised to brand its debut. Asus was scheduled to send the high-cease P6X58 Premium motherboard with USB 3.0 ports provided past NEC'south host controller (for the uninitiated, the traffic cop for external devices), but the company appear a slight delay. NEC's host controller just obtained the first USB 3.0 certification of whatever host on September 21, however, then that Asus board should run into the calorie-free of day before long.
A few more than motherboards equipped with USB iii.0, all using NEC's host controller, should ingather up afterward this year, and Fujitsu is close to releasing a laptop with USB 3.0 ports. USB iii.0 ports will get far more mutual on laptops and desktop PCs throughout 2010.
All the ports in the world are useless without uniform devices, of course. We saw a demo at IDF 2009 of an external solid-state drive with a USB 3.0 connection by LucidPath that accomplished a transfer rate of over 240MB per 2nd (and if you've ever used an external USB hard drive, yous'll know just how much faster that transfer rate is). These sorts of mass storage devices should exist the start to hit the market, starting early in 2010.
Expect video cameras to start using USB 3.0, too. Point Gray has demonstrated a high-def Webcam that uses USB 3.0, though information technology isn't even so a shipping product. Unlike current USB Webcams, this USB three.0 model does not have to shrink the video feed earlier sending it to the PC. SuperSpeed USB is fast enough to transmit the raw, uncompressed Hd video to the PC for capture or compression, which tin can profoundly improve the video quality and make loftier-def Webcams cheaper, too. Devices like these volition arrive a piddling later in 2010, but y'all should run into all sorts of products conveying the SuperSpeed USB label on store shelves by the cease of 2010.
None of this means that USB 2.0 is going anywhere, of course; it volition keep to be the more affordable choice until USB 3.0 controllers come congenital into the I/O host controllers of motherboards (the NEC USB three.0 host controller mentioned in a higher place is a separate chip on the motherboard, and is not function of the motherboard'due south main host controller). And USB two.0 is still suitable for input devices–mice and keyboards don't require all of the available bandwidth that SuperSpeed USB promises.
Yet, it's good to know that the college-speed, lower-power, faster-charging cabled time to come is almost upon the states. Peradventure your future 128GB iPod, Zune, or smartphone won't take two hours to fill up with music.
