Traut, I have read a white paper on external drives reliability. It was created by the company selling backup solutions but their findings were valid nevertheless.3'5 drive dissipates heat through heavy cast metal frame, not through the thin cover at the top. Touch one in your PC and you can feel it.
Most but not all external drives made of aluminum are in direct contact with the drive's lid, not with the cast metal frame. Frame is usually in contact with the sliding rail and rail has limited contact surface with the aluminum body of the enclosure.
As a result, many external drives warm up like toaster. Many enclosures are even made of plastic, not metal. I do not want to think if there are some noxious evaporation from the hot plastics, having in mind it was made in China with no environmental control (lead was found in plastic the toys are made of).
I have had a bad experience with an external drive made by well known accessory manufacturer. The external power supply started heating so much that the external plastic got melted. Drive crashed before I noticed foul smell of burnt PS. Think about it - $30 drive enclosure uses $1 power supply and both your data and your house relies on it operating well.
I almost got my house on fire because PS was sitting on the carpet. This experience made me think twice before purchasing any device that will be connected to AC for a long periods of time.
