Perhaps no USB3 solution ready?
PROMISE Technology Inc. rolled out its Pegasus line of high-performance hardware RAID storage systems, the first peripheral devices to employ Intel's Thunderbolt IO technology for data transfers among multiple devices and device types that use different protocols, using a single cabling technology.
Developed in conjunction with Apple, Intel's Thunderbolt is an interconnect technology that provides a leap in performance over current I/O technologies with 10 Gbps of full-duplex bandwidth per channel. It concurrently supports data (PCI Express) and display (DisplayPort) connections over a single cable.
Utilizing Thunderbolt technology high-speed I/O, Pegasus can deliver performance up to 864MB/s, more than 20 times faster than USB 2.0 and 12 times faster than FireWire 800, according to the company. Pegasus is offered as a 4-bay or 6-bay RAID enclosure supporting seven RAID modes including RAID 0, 1, 5, 6, and 10,. Pegasus features two Thunderbolt Technology ports, an aluminum enclosure and a smart fan for reduced system noise.
Pricing and Availability
Pegasus hardware RAID solutions are available through the global network of PROMISE distributors and value added resellers and from the Apple Store (www.apple.com) MSRP for a 4-bay 4TB configuration is priced at $999, with a 6-bay 12TB priced at $1,999.

I really love the technology, but I'm not so sure about the price point of this product.
With little effort I can buy 4x 1TB drives ($54.99) and a 4-bay eSATA enclosure ($126.99) for a whopping $367.
Second, the Pegasus can only transfer a maximum of 6.75 Gbps, which is only 3.75 Gbps faster than existing eSATA technology. Call me cynical, but I don't think an extra $632 is worth 3.75 Gbps. /rant

Why the comparison is done against USB2 not against USB3? Kris

I think USB3 is is already shipped in laptops, see this Wikipedia entry:
USB 3.0 is the third major revision of the Universal Serial Bus (USB) standard for computer connectivity.
USB 3.0 has transmission speeds of up to 5 Gbit/s, which is 10 times faster than USB2.0 (480 Mbit/s). USB 3.0 significantly reduces the time required for data transmission, reduces power consumption, and is downward compatible with USB 2.0. The USB 3.0 Promoter Group announced on 17 November 2008 that the specification of version 3.0 had been completed and had made the transition to the USB Implementers Forum (USB-IF), the managing body of USB specifications.[1] This move effectively opened the specification to hardware developers for implementation in future products.
The first USB 3.0 consumer products were announced and shipped by Buffalo Technology in November 2009, while the first certified USB 3.0 consumer products were announced 5 January 2010, at the Las Vegas Consumer Electronics Show (CES), including two motherboards by ASUS and Gigabyte Technology.[2][3]
Manufacturers of USB 3.0 host controllers include, but are not limited to, Renesas Electronics, Fresco Logic, Asmedia, Etron, VIA Technologies, Texas Instruments and Nvidia. As of November 2010, Renesas is the only company to have passed USB-IF certification, although motherboards for Intel's Sandy Bridge processors have been seen with Asmedia and Etron host controllers. On October 28, 2010 Hewlett-Packard released the HP Envy 17 3D featuring a Renesas USB 3.0 Host Controller several months before some of their competitors. AMD is working with Renesas to add its USB 3.0 implementation into its chipsets for its 2011 platforms. At CES2011 Toshiba unveiled a laptop called "Toshiba Qosmio X500" that included USB 3.0 and Bluetooth 3.0, and a new series of Sony VAIO laptops that will include USB 3.0. As of April 2011 the Inspiron and Dell XPS series are available with USB 3.0 ports.
