PS3 Vertical = bad???

[nordlead]

I have read (although, I'm not 100% sure) that vertical for any disc drive is harder on the drive than horizontal.

The supposed reasoning goes something along the lines of this.

When in the horizontal position, the motor doesn't have to fight gravity while spinning the disc, which means it has even forces on the motor.

In the horizontal position the motor now needs to fight gravity on 1 side of the disc (the side traveling up) and has the help of gravity on the other (side going down). This causes uneven forces on the motor which could break it prematurely.

Now, I'm not going to do any research on it, but my own little evidence is that my Wii (maybe I knocked it over too many times) makes more noise in the vertical position than it does in the horizontal position while spinning the disc.
