This question already has an answer here:

I've bought a couple of 3.5 inch desktop hard drives for downloads and storage. They are Seagate Expansion which is the “vertical” version. (that means the spinning disc inside is perpendicular to the table surface) I hope you guys know what it is like… it’s so common

However, I have concerns that a desktop drive that is vertical is not good for its health for long term, since it’s not like internal drive that mounted inside the chassis securely… It looks more comfortable for me to see it lies horizontally.

Is it an unnecessary worry?

  • Either position is fine, just don't move it while it's in use. – QMord Nov 1 '15 at 6:07
  • In theory and according to manufacturers it makes no difference. In real life disaster recovery situation I have seen drives which I can recover data from only in certain orientations, but which fail in others. But I couldn't tell you why. – Kilisi Nov 1 '15 at 6:14
