There's no comparison with the ship's machinery. That was designed by very conservative naval architects, and the propulsion system has far greater forces to deal with than gyroscopic effects. I don't think it's totally implausible a disk drive not designed for a moving environment could cut loose... but those things were over-engineered quite a bit too. So I for one abstain for the time being.
