I have been having similar experience and I have decided to order (this week) the NewerTechnology miniStack external HD and enclosure. They have several options for connections and you can determine the size of the hard drive that you want. They daisy chain and stack on top of another. Find them at Other World Computing (macsales). Check them out. They are nice people to deal with.
