USB 3.0 technology is now a consumer reality. According to CNet News Buffalo Technology is officially the first company to ship a USB 3.0 hard drive. The SuperSpeed USB 3.0 external DriveStation HD-HX83 is available now in 1 TB, 1.5 TB and 2 TB sizes. Buffalo is also selling a two-port USB 3.0 PCI card in order to allow users to upgrade their PCs as well.
USB 3.0 currently delivers data at speeds about 3x that of USB 2.0 devices. However, it's worth noting that all USB 3.0 technology is fully backwards compatible. You can plug this new HD into your existing machine and use it just fine, albeit at USB 2.0 speeds.
Buffalo states that their drive is now shipping out to Microcenter, and should be available for purchase by December 7. The 1TB drive should cost $199, while the 1.5 TB will cost $249 and the 2TB will cost $399. For more information, check out the product's website here.
