Disc drive noise/clunk question on new console with energy saving mode on

Hi guys, just picked up a new console to replace my old one, so far everything seems perfect. Quick question though, perhaps due to my paranoia:

If you watch this video (disregard the point of the video its simply the only video I found with the noise I am describing haha) , on around 1:59-2:00, immedietly after inserting the disc and the drive closing, you hear a single
read clunk, and then the disc spins and works as normal.

This single clunk only happens on the very first disc insert after a cold boot, since i have mine set to energy saving, i hear it everytime i forst insert a game after turning on the system. Any discs inserted after dont really make this sound.

My first Xbox had drive issues, so my paranoia about any clunks is kinda high. This drive works perfectly, apart from that first disc insert clunk from cold boot.

What do you guys think this initial clunk is? Just the disc drive mechanism?

Thanks for any help! Again, it's the clunk immedietly at 2:00, prior to the drive spin.

X1 making noises while off

Mine makes a faint ticking noise. I think it's just he fan. If your worried about saving energy, turn on energy saving mode to turn your box completely off.

 

Xbox One S making humming noise while Off, normal?

If it is turned off using the energy saving mode there should not be a humming noise coming from the console.
