Superspeed USB needs chipset integration
ACCORDING MARKET RESEARCH FIRM Instat, Superspeed USB, which has been around since last year, will mature slowly, despite offering ten-fold bandwidth improvements.
Although Instat thinks that USB 3.0 will have a thirty per cent share of the USB interface market by 2014. It believes that growth will start slowly and will only increase once devices with it built-in start hitting the shelves.
"It will take time for SuperSpeed USB to be integrated into the core logic PC chipset," said Brian O'Rourke, an Instat analyst. "USB achieved its immense success primarily due to core logic integration, which effectively allowed PC OEMs to offer it for free. Integration is essential before a new USB standard becomes prominent in PCs."
USB 3.0 core logic chipsets will arrive in late 2011 the analysts added, and shipments of the technology will grow accordingly, by about four fold between after that through 2013.
The full report costs about £3,000. µ

Not to say that this report isn't worth the price of an early view of the next iPhone (not counting police raid and prosecution), but if USB 3.0 is ready, why are we waiting? Why haven't chips been developed already with USB 3 support, or with space onboard for it? Say with USB 2 in place on last year's model, ready to be swapped out for shiny new USB 3 in chips going into PCs now?
As for interoperability issues... that comment just described the business of operating USB 1 and USB 2 devices together. We know about that. Some of us are still doing it. The straightforward approach is to use at least one of your USB ports for faster devices only.
What people don't realise is USB 3.0 requires the chipset to be USB 3.0, the device to be USB 3.0, the cable (yes, you need a special USB 3.0 cable, otherwise you get USB 2.0 speeds), and you can't have a USB 2.0 device plugged in to the same hub as it will slow it to USB 2.0 speeds.
Intel is due to release a new generation chipset for the socket 1366 core i7's later in the year, wonder whether that has USB 3.0. Knowing Intel, no!
"It believes that growth will start slowly and will only increase once devices with it built-in start hitting the shelves."
Only a consultant could sell sell something so obvious.
First USB 2.0 Got to Go, entirely. Forget Backward Compatible, USB 3.0 Is Too Fast & precious. So special adapter for serial port for usb 2.0/1.1/1.0 or just chuck stuff, everyone does. Maybe use parrell port. maybe do Firewire Usb 2.0/x combo external. Anything except backward compatible into superspeed USB porting. OLDEE' = JUNK.
Next getting entire Speed. Good, on Way. Plug SSD into it. By then cards really will be 16x & finally 32x pci-e 3.0 slot Is Mine. Big Displays, Big Monies, Big time.
PS Time is constant, it can go neither faster nor slower,EVER.. Except in imagination.

If you're going to provide a 4Gbit/sec IO channel then at the very least it's going to need a couple of PCIe lanes to handle it.
Trying to graft on that kind of performance to existing machines without chipset support is going to bottleneck heavily, but then what do you have that can saturate that kind of bandwidth anyway?
Just built a new PC with USB 3.0. eSATA used to be my preferred interface to external HDD. Not any longer. Why settle for 3 Gbps when you can get nearly 5 Gbps and the convenience of a USB connected device?
Demand will likely 'encourage' a speedier adoption.
It is too bad that it will take so long for USB 3.0 integrated chips to start selling for OEM. I know it is cheaper to keep pushing 2.0 but come on. You have many other companies producting USB 3.0 products. Consumers are ready for this upgrade and someone is dragging his feet. We should start seeing OEM USB 3.0 in the second half of 2010, not in 2011. Quit stalling!
