While that is what they hoped to achieve, you must realize this is based on moving a single instance of raw data. What comes into play is how many devices are trying to talk over it. 12 to 40 mbps is more the norm.Quote:

USB 3.0
On September 18, 2007, Pat Gelsinger demonstrated USB 3.0 at the Intel Developer Forum. The USB 3.0 Promoter Group announced on November 17, 2008, that version 1.0 of the specification has been completed and is transitioned to the USB Implementers Forum (USB-IF), the managing body of USB specifications.[31] This move effectively opens the spec to hardware developers for implementation in future products.
A new major feature is the SuperSpeed bus, which increases the maximum transfer rate to 5.0 Gbit/s. [32]
USB 3.0 receptacles are compatible with USB 2.0 device plugs for the respective physical form factors. However, only USB 3.0 Standard-B receptacles can accept USB 3.0 Standard-B device plugs.
The protocol uses Dual-simplex, over four additional wires, differential signaling separate from USB 2.0 signaling (thus six wires total) to achieve the full Superspeed 5.0 Gbit/s[33]
The protocol supports full-duplex data transfers.[34] In addition, data transaction is based on asynchronous traffic flow with explicitly routed packet traffic, instead of the polled broadcast packet traffic in USB 2.0. A streams mode is added for bulk transfer mode. SuperSpeed protocol also supports continuous burst transfers.
New power management features include support of idle, sleep and suspend states[33], as well as link and function-level power management.
Maximum bus power is increased to 150mA per unit load (+50% over USB 2.0). An unconfigured device can still draw only 1 unit load, but a configured device can draw up to 6 unit loads (900mA, an 80% increase over USB 2.0). Minimum device operating voltage is dropped from 4.4V to 4V.[33]
USB 3.0 does not define cable assembly lengths, except that it can be of any length as long as it meets all the requirements defined in the specification. However, electronicdesign.com estimated cables will be limited to 3 m at full speed.[16]
The technology is similar to PCI Express 2.0 (5-Gbit/s). It uses 8B10B encoding, linear feedback shift register (LFSR) scrambling for data, spread spectrum. It forces receivers to use low frequency periodic signaling (LFPS), dynamic equalization, and training sequences to ensure fast signal locking.
Availability
USB 3.0 devices supporting SuperSpeed bus are expected to be available in commercial controllers in the first half of 2010. However it will not be until the second half of 2010 when they become seen on products other than computers. Consumer products are expected to become available in 2010.[35]
Windows 7 and Linux drivers are under development but no public releases have been made available as of February 2009
ITS A brando 16 hub, and its about 150.00.
im not for sure if i want to spend that much , but who knows.
