Delay will greatly impact USB 3.0 adoption in 2010

When it comes to backing up large amounts of data, many computer users will agree that USB 2.0 speeds are simply not fast enough. This has led to eSATA and other connectivity solutions that can provide more bandwidth than USB 2.0 is capable of for the storage industry.

Those looking forward to the wide rollout of USB 3.0 will be saddened to hear that the specification has been dealt a setback. This summer, expectations were that USB 3.0 devices and computers supporting USB 3.0 would be available before 2010.

A source at a top-tier computer maker has confirmed to EETimes that USB 3.0 support in key Intel chipsets has been postponed until 2011. Support for USB 3.0 was expected to show up in early 2010 for Intel chipsets. The same top-tier PC maker source also told EETimes that wireless USB was effectively dead. Rather than moving to wireless USB, which has had many supporting startups and interest groups close up shop, the industry buzz is now focusing on 60 GHz technology.

With Intel not offering wide support for USB 3.0 in its chipsets in 2010, adoption of the specification will reportedly be limited to a few high-end graphics workstations and consumer PCs. The makers of these systems will be forced to buy discrete host controllers for their boards, which will make the parts high-cost items.

The unnamed source added, "It's hard to commit to an emerging technology like this (USB 3.0) when the key silicon enablers are not making it a priority. You get into a chicken-and-egg situation." USB 3.0 "won't get real traction until it gets integrated in the chip sets," said the source.

As for why USB 3.0 was postponed after a big showing at IDF, the source told EETimes, "Tech and strategy groups (at Intel) are not always aligned with the product development teams that are in the mode of trying to make revenue and prioritize what to integrate."

Why is USB3.0 needed again?

eSATA works, is cheap, and is becoming more common on motherboards.

USB3.0 has the advantage of power but it doesn't have enough capped at 4.5W that isn't enough to run all 3.5" drives. The 15W firewire provides would be more universal.

SATA 6Bps will provide more than enough bandwidth. Simply update the eSATA spec to have a backwards compatible connector & cable that supports data & power.

would have been nice if they had added firewire then we would atleast have had a standard interface :/

from what ive heard about eSata you have to start the computer with the device hookedup or reboot to get it working..

my motherboard didn't come with esata so ive never tested it, but if the above is the case this tech sux.

just give us some USB3 add-in cards and a hdd dockingstation, pmp's, external hdds, and flash few drives and all will be forgiven =)

Not if you configure it in AHCI mode in BIOS.

The issue with eSATA is that it still is a port that's not as widely used and available as USB is. So having USB3.0 lets you get the performance from systems that support it and also be able to use it on older USB standards which is available almost on 99.9% computers nowadays, if not 100%. eSATA was not available on >90% of existing systems and even now is available on maybe few desktop motherboards and almost 1-5% on laptops. So the USB3.0 is a better option over eSATA, even when LightPeak comes out - ease of finding a system with the USB port.

There is also the issue of cable length for eSata. The max cable length is
"Maximum cable length of 2 metres (6.6 ft) (USB and FireWire allow longer distances.)"
http://en.wikipedia.org/wiki/Esata#External_SATA

While 6 feet seems like a lot for cables, when you can get USB printer cables of 25-50 feet that can be daisy chained, you can setup confrence rooms not looking like crap.

Uhh no, you can't get USB printer cables of 25-50 feet unless they are violating the spec, USB max is 15 feet and requires pretty good quality cable for that or some devices won't work.

You are totally ignoring better tech for the purpose, there are tons of wifi and ethernet capable printers on the market, actually almost any decent quality printer supports one or the other if not both.
