I actually found your comment on another video of an LPS drive, asking for a better spin up. I uploaded this because of that, since I forgot I recently came across this drive. I've never heard one this quiet. At least, not since I was a very little kid in the 90s.
@@redleader6442 Same for me, never heard one with such quiet bearings. Also I had no clue the LPS stood for "low profile series", I thought it was something to do with the optical encoder to keep track of the head positioning.

LPS actually originally stood for "Light Positioning System" which is a quantum thing. Uses a light sensor (as the name implies) to position the heads. These things have the very sad rubber issue that plagues prodrives. Maybe fix it before it fails?

Excellent example indeed....very pleasant to hear one that is healthy and in great shape!
