Seagate is offering a great new portable drive. I like the new design better then the previous slanted FreeAgent drives. This device has not only a 7200RPM drive but support separate cables that provide USB 2.0/3.0 , Fire wire 400/800 and eSata just by swapping the cables.
There is also a NAS attachment for it. They pro version 1TB are on preorder at Amazon and I look forward to there release.
