Xbox series x and series s inBeta Ring Powering Off unprompted. Rolled series S down to...

They're rolling it out slowly to everyone, I have it on my series S and on my One X, but not my series X

The Series X is physically larger than the Series S and has a disc drive where the Series S does not. The X will be more powerful and run games in true 4K.

This article has a pretty good side by side comparison of the specs. https://www.pcmag.com/news/xbox-series-x-vs-xbox-series-s-whats-the-difference

You should be able to do that, yes:

"Power down your Xbox One.

1. Unplug the external drive.
   
2. Connect the external drive to your Xbox Series X, S.
   
3. Power on your Xbox Series X, S.
   
4. Wait for the external drive to be detected. This may take a couple of minutes.
   
5. When the drive is detected, you are free to copy any games you want onto the Xbox Series X, S internal storage."

"The Xbox series S is a more than capable gaming console with an excellent power to price ratio that targets 1440p and can output upscaled 4k.

As a result you should not be getting significantly noticeable 'pixalation' over the series x."

The original poster bought an Xbox One S, not a Series S and was comparing it to an Xbox One X, not a Series X.

You mean xbox one s

Not series ?

Xbox series s isn't the same as xbox one s

Xbox one games are just xbox one games .

Series consoles have s or x requirements physical or digital plus the power difference
