USB 3.0 to get upgrade to 10Gbps by 2014
Expect the transfer speeds of USB 3.0 to be doubled from the current 5Gbps to 10Gbps by 2014. The news comes from the USB 3.0 Promoter Group at CES this week. New controller hardware is required for this to happen however, so current generation USB 3.0 devices will still be stuck at their current 5Gbps transfer speeds.
In addition, the SuperSpeed USB cables may well be needed too, though the revised USB 3.0 standard will offer backwards compatibility, since it will use the same connector plugs.
The announcement comes at a time when the competing 10Gbps Thunderbolt interface is still struggling for traction, almost two years after its appearance on Apple's (NASDAQ: AAPL) MacBook Pro line of laptops in the early part of 2011.
For sure, Thunderbolt's lackluster pickup has nothing to do with its performance; a single Thunderbolt cable offers two channels of full-duplex 10Gbps data transfer. Because it hooks directly onto the PCIe interface bus, heavy data transfers also hog fewer system resources.
Part of the blame has been attributed to its high implementation cost. Intel (NASDAQ: INTC) had previously pledged to support both USB 3.0 and Thunderbolt in 2012 though. Additionally, reports of fiber optic Thunderbolt cables also surfaced last week, which suggests the arrival of 100 ft. Thunderbolt cables soon.
