7 mobile hard drives: More portable and more powerful

Bottom line

While some of these portable hard drives are a bit better than others when it comes to design, performance, warranty and bundled software, there's really not a bad option in the group. Corsair, Seagate and Western Digital share the speed crown, while Corsair and Patriot get points for severing the USB cord altogether -- though Patriot's model wins the day by being more compact and less expensive.

How important is speed, anyway? For some users, it won't be at all important, as any of these units will blow your existing USB 2.0 drives out of the water. That said, if you want really fast file transfers, look to the drives from Corsair, Seagate and Western Digital.

You should also consider each drive's warranty. While the average is two years, some models are covered for only one year, while a few raise the stakes to three. Obviously there's no way to predict when a drive might fail on you, but a longer warranty does suggest greater durability.

Whatever drive you pick, you're likely to enjoy high-speed file transfers and a barely noticeable bulge in your carry-on -- the real joys of portable storage.
