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.

Hong Kong gadgeteer Brando can sometimes score a rare hit. We offer this SATA HDD Multi-Media Player Adapter as proof. This small adapter lets you plug in any SATA hard disk, SDHC card, or external USB drive, and play back its media with no computer anywhere. How sweet is that?

You have to wonder about the interface presented to you when you plug it into your TV via HDMI, component, or composite inputs. But even if it’s horrible, you’ll be able to view all kinds of audio and video formats on your TV, including MPEG-4, DivX, and AVI, without a PC anywhere nearby. That’s pretty convenient.
