Protect Your Files
A catastrophic hard-drive failure isn’t a matter of if, but when. Consider the D-Link DNS-323 your peace of mind. Connect it to a router and it can wirelessly back up data from multiple computers. Everyone in the house can access it, too, making it the perfect place to store MP3s. Thankfully, you can block other users from seeing more, um, personal files. [$200; dlink.com]
