Sure this isn’t the most attractive or exciting device ever, but in terms of practicality, it’s pretty cool. Aleratec’s 1:1 HDD PortaCruiser Lightweight and Portable Hard Disk Drive Duplicator lets you easily clone 2.5″ and 3.5″ hard drives for backing up your data.

It also functions as a Dual Disk RAID Controller so you can attach two hard drives to it, connect it to a USB 2.0 port and use it as external storage. The 2-line LCD display makes things even easier. And it weighs only 8 ounces, so you can carry it with you.
