Why doesn't my laptop have USB 3.0?. I've been asking myself that question a lot lately.
It's 2011. That should be a USB 3.0 port on the 2010 MacBook Air. But it's not necessarily Apple's fault. All laptops should have had that 10-year-old USB 2.0 port updated years ago.(Credit: Apple)None of my laptops has a USB 3.0 port. Not my 2010 MacBook Air, not my prior-generation Air, nor my Dell laptop. Nor do the laptops purchased recently by my business acquaintances, who typically buy earlier models that have been price-reduced.Let me be clear, I've talked to Intel, folks at the USB Implementers Forum, PC makers, and analysts. And I've heard every reason under the sun as to why the Universal Serial Bus interface hasn't been upgraded in 10 years. (Intel: We'll get around to it in 2012.)But those reasons (including: it won't make any material difference for things like printers...not supported in Intel silicon) don't change the fact that devices I use demand a faster USB interface. Now. Or I should say yesterday: I needed it a long time ago.
Thunderbolt, as promising as it sounds, does nothing for consumers today.
I'll be honest, I had completely forgotten about USB 3.0. All this hubbub about Thunderbolt took my mind right off of it. Thunderbolt has the ability to connect multiple devices such as HDD's and TVs in order to stream media and transfer content at ludicrous speed.
But why haven't we seen more USB 3.0 support inside of laptops and other computers? I think it's safe to say we can blame Intel for their lack of adoption in their chipsets. Even if that's not the case, I'm still going to blame them just for the article's sake. It's silly to think that we've been on USB 2.0 for so long. It should take just seconds to sync our cell phones to our fancy iTunes and move over all my episodes of Doctor Who. Seconds!
Now, it's entirely possible that we may skip USB 3.0 in favor of Thunderbolt. Apple had begun using similar specs to connect to their flat-screen panels, and now the same plug can be used to transfer files at warp speed. It's likely that in future products, Apple could use Thunderbolt for their iPhones and iPads. You could, in theory, sync your iOS device in 5 seconds. Yowza!
Still, I'd love for us to get to a place were we don't need these wires, but I don't think we're there yet. We may not even be there for several more years. If you have a healthy helping of media you need transfered at light speed, be sure to contact us at Trigon and we can help you have more time for Doctor Who.

. As a follow-up to my previous article, USB 3.0 (also known as SuperSpeed) devices are now starting to be made more available. According to the website
, Belkin has two peripheral cards available. One is a PCIe card that can be installed in Desktops and the other is a PCMCIA card that can be connected to laptops. Belkin has also developed two different styles of USB 3.0 compliant cables - a SuperSpeed A-B cable and a SuperSpeed Micro-B cable that can be used to connect USB 3.0 compliant devices to USB 3.0 capable systems.
Belkin has also shown in tests that data transferred over a USB 3.0 connection is 3x faster than USB 2.0 in real-world tests. Theoretically, USB 3.0 can transfer data at 5 Gbps, which is ten times as fast as that of USB 2.0 (480 Gbps). With speeds this fast, watching a Blue-Ray disc in high-definition will be no problem at all, provided your system has the capability of adding a USB 3.0 card for compatibility and viewing high-definition video.
There is also a good PC World article that gives a little bit of background into where USB 1.1 and USB 2.0 started, as well as talking about the compatibility guarantee of USB 3.0. Previously, a number of devices claimed to be USB 2.0 compliant but that is only because of the fact that they were low-speed devices. USB 3.0 has to be capable of delivering 5Gbps speeds in order to qualify for SuperSpeed compatibility.
As was stated in the previous article, more devices will be coming out with USB 3.0 capabilities, but now there are options from Belkin on getting non-USB 3.0 capable systems to be able to attach USB 3.0 devices. Most likely there will also be other vendors in the future, but items are currently available from Belkin for adding USB 3.0 to a system not having SuperSpeed abilities right now.

Have you even heard about USB 3.0 yet? If not, I am sure you will in the near future (besides reading this blog). Well, the 1.0 specification for the new technology has been out for almost a year now, so at some point there will be devices that support the latest version of the USB standard (nicknamed SuperSpeed USB).
According to this website (http://www.everythingusb.com/superspeed-usb.html), there are a number of ways in which USB 3.0 will be better than its predecessors. For one, it will be backwards compatible with both USB 1.1 and USB 2.0. Other improvements upon the USB 2.0 specification will be: higher transfer rates (theoretical maximum of 4.8 Gbps vs. 2.0s limit of 480 Mbps), more power available to devices, power management features, full-duplex data transfers (as opposed to the half-duplex of USB 1.1 and 2.0), and new connectors and cables for devices.
A couple of the drawbacks of USB 3.0 is that it will be more expensive than USB 2.0, due to the necessity of including USB 2.0 support (a separate interface for USB 2.0 is needed, rather than being included in the new connections), and there is not the wide-spread support yet for USB 3.0 that there is for USB 2.0. In coming months, there will most likely be devices and controllers that will be coming out that will aid in the increase of USB 3.0 but as of right now, even the newly released Windows 7 Operating System does not support USB 3.0 (most likely will be included in the first Service Pack).
Negative items aside, this will improve the performance of externally connected devices that require more than the existing USB 2.0 can provide. The biggest area that this will improve will be in the multimedia and data storage realms. Video will be more streamlined and audio performance will be enhanced. Large data transfers will take much less time and allow new devices to be put into use that it would be pointless to implement over USB 2.0 (such as large externally-connected RAID systems).
I am sure that it will take time for USB 3.0 to be more prevalent than USB 2.0, but once devices start coming out that take advantage of the higher throughput and power features, it will only be a matter of time. Similar to DVDs and CDs, I think that USB 2.0 will still be around for quite some time once USB 3.0 is available due to the nature of cost and usefulness. After all, how many more seconds are you going to save transferring a 100MB file onto a USB 3.0 flash drive than you will onto a USB 2.0 flash drive?
