Seagate's new Wireless Plus portable harddrive has 1TB—double that of its predecessor, for the same $200 price. It lets you stream to your iPad by creating its own Wi-Fi network. It's very useful—that is, if you have very specific needs.
With LaCie, you always expect the product to look good—and the Rikiki portable HDD is no exception. They also claim that it is the smallest 2.5-inch drive on the market.
I don't ask much of portable hard drives: they should be affordable, easy on the eyes, and better not require an external power source. So I kinda like Iomega's pretty, cheap(ish), USB-powered eGo drives.
We're still more than excited about USB 3.0, but those of us expecting it to reach promised transfer speeds of 5000Mb/s this year are overly optimistic.
There has been a ridiculous amount of news this past week about portable hard drives of the 2.5-inch variety. OWC introduced a 160GB 7200rpm portable. Samsung did one better announcing a 200GB 7200rpm 2.5-inch drive, but that was a tease: It would initially only be available to enterprise customers.
