60gb ocz vertex 2 as my boot drive because it was one of the cheaper ssds on the market at the time.
500gb wd scorpio black for general storage because I did a case mod for myself and couldn't fit a 3.5" drive.
1tb wd caviar black for steam so I can play whatever on any of the computers at home without needing to download again and again.
3tb wd mybook live for media storage because there are multiple devices (phone, tablet, 3 computers, ps3) that can all play music and videos from the drive.
