Why USB Wins Over Thunderbolt

Thunderbolt is the new technology by Apple which is claiming better performance and speed then our new USB 3 specification.  It all looks good on paper and plan, but will reality let Thunderbolt win? Thunderbolt is the copper wire version of Intel’s Lightpeak technology.  Thunderbolt will produce transfer rates equal to 10Gbps which is about double of what USB 3 will offer. Apple convinced Intel to create a “cut-back” version of their optical light solution with an additional caveat of being the exclusive personal computer manufacturer to offer Thunderbolt.  And this is where the problem lies. As with USB 1 verse Firewire [Apple] the speeds of Firewire where faster than USB 1, but FireWire equipment was more expensive, Apple charged what was considered a substantial royalty per part, and with Macs in general holding much less of the market, meanwhile the Windows-side controllers and drivers for Firewire ran the gamut from lousy to terrible. Intel and Apple jointly developed Thunderbolt, which may actually be part of the problem.  As of June 2011, Apple is the only company committed to using Thunderbolt.  HP has officially selected USB 3 and we suspect Dell will not be far behind.  After all, these guys don’t like to support a technology to a competitive company which holds Continue Reading

PQI Now in USB 3.0 USB Drive Market

PQI introduced their first SuperSpeed USB 3.0 flash drive today, called the U339V.  The PQI 3.0 stick is available in 8GB through 64GB sizes.  As with any new technology, the performance is lagging behind the specification of performance.

PQI USB SuperSpeed 3.0

For example the smaller 8GB PQI drive shows a read speed of 55MB/s and a write speed of 10MB/s.  Verse the larger 16GB and larger sizes are more like 86MB/s read speed and 20MB/s write speed.  If you know anything about flash drives, it just means the bigger sizes are dual channel and the 8GB is single channel. Still far from the 5Gbps transfer rate USB 3.0 is suppose to offer, but once more advanced controllers come into the market, we’ll see the performance rise. The PQI drive will be available through Continue Reading

Sony VAIO Laptops Shipping SuperSpeed USB 3.0

When Sony officially supports the USB 3.0 specification by supplying a dual USB 3.0 port on their new VAIO laptops, it’s safe to say the transition is picking up steam.

Sony VAIO USB 3.0

The Sony desktop-replacements are HD VAIO laptops coming with possibly everything you can hope for with the exception of 3D and SSD. The more expensive model ($2,970) will have Core i7-740QM, GeForce GT 425M 1GB graphics card while the lower end laptop ($2,140) will only carry a Core i5-460M and GeForce 310M 512MB. Both Sony VAIO models are stocked with 4GB RAM, the same Blu-ray optical reader, 500GB 2.5″ drive and a dual HDTV tuner as well as a 16.4″ full HD LCD. In the connectivity department, both laptops will feature not one but two USB 3.0 ports – likely powered by Continue Reading

SuperSpeed USB 3.0 Connector

Now that SuperSpeed USB is out what does the physical connector look like?  Well, GetUSB isn’t 100% sure but we’ve seen some images popping up on the internet. First, lets take a look at the USB connector we reported about in Januarary of 08:

Now we have a new image coming up from UberGizmo which might be a more developed connector of the SuperSpeed USB connector:

Once we get word on the official socket / jack we’ll report back. Continue Reading

SuperSpeed USB 3.0 Version 1.0 Is Officially Available

SuperSpeed USB logoOn Monday the USB Implementers Forum released the official documents for SuperSpeed USB 3.0.  We’ve been reporting on the SuperSpeed for about 6 months and it’s finally come to fruition.  The logo to the right might be the USB-IF official logo as we pulled it directly off their press release material. What we have today is the specification outline, meaning we don’t have products yet, but now developers and chip manfucaturers have an official outline of how to build USB host controllers, hubs and other logic devices to manage the super speed of USB 3.0. The new specification claims transfer speeds of 4.8Gbps [Gigabits per second] rate which translates to a data transfer rate of approximately 600MB per second. So what next?  Well, between now and the next year, manufacturers will be in a mad rush to get Continue Reading

SuperSpeed USB Spec Released by Intel

superspeed usbIntel released a draft specification for USB 3.0 or SuperSpeed USB. The Extensible Host Controller Interface or xHCI provides a standard method for USB 3.0 host controllers to communicate with the USB 34.0 software stacks. Both AMD and Nvidia voiced complaints earlier in the year that Intel hasn’t released update information to make the new spec an open industry standard and an easy path for transition. Today’s release is Intel’s answer to that request. Dell, Microsoft and NEC also support the release because the xHCI will expedite the industry transition to next-generation USB 3.0 technology.
One important factor in adopting SuperSpeed USB products is interoperability between multiple devices from different manufacturers. The xHCI draft specification revision 0.9 aims to make interoperability easier to implement, while also making it easier for developers to create software support for the market.
The next revision update is expected at the end of 2008 with revision number xHCI 0.95. So no SuperSpeed USB yet, but the big boys are working their way to it. Source: CRN. Continue Reading
