Anyone know of the best thunderbolt portable drive to do this with? I have a 512GB SSD drive (Samsung), and I want to get a thunderbolt enclosure and put the drive in and have my OS boot off of it, so when I'm home I boot my iMac off it and have my OS on it at home, and then when I'm on the road I unplug it and plug it into my MacBook Air and have the same OS setup on the road. My only concern is there are seemingly no external thunderbolt enclosures on the market, but I've heard several people have taken external TB drives, and opened them up, replaced the hard drive with a SSD then closed em back up and had wicked-fast boot experiences with the drive. Since I already have the 512GB SSD, the biggest cost is out of the way. Any advice would be appreciated!
