makes no difference - gravity is insignificant compared to the other forces acting on the components. At least one of the manufacturers state this, others do say it should be oriented horizontally OR vertically in either direction, but this is most likely down to testing more than anything else. I used to have links to that effect, but tbh I can't be bothered to find them again. I might even have posted them on OCN at some point - this kinda question crops up from time to time...

i think it would though. centrifugal force is like gravity. so I'm sure stress forces act differently on the drive motor in different orientations...... whether that makes it wear out faster might be another story though......

centrifugal force is not like gravity - it's centrifugal force (although actually in this case it's centripetal force you're worrying about).

But as the forces due to the HDD motion are orders of magnitude higher than those due to gravity (7200rpm is fast, and the armature assembly is light) you don't need to worry about gravity.
