I have switched to an Xbox series X from an Xbox one S. we used an external sea gate hard...

This article explains the difference between using a regular external hard drive versus the custom external storage for the Series S/X- https://news.xbox.com/en-us/2020/09...xbox-series-s-custom-storage-solution-primer/

An external hard drive used on the One will work for the Series S/X, but won't have the exact same performance as the one created for the Series S/X.

Hi,

Your drive will work the same on Series X as it does on Xbox One and you won't need to format it.

However, Series X games or Xbox One games with Series X enhancements will not run from that drive and will either need to be installed internally or to an external SSD designed for Series X/S.

Your hard drive will be too slow for Series X games. They can be stored there, but not run from there.

You can use the drive, but games that have been optimised for Series X|S can only run via either the internal SSD or a 1TB Expansion card.

You can archive your X|S games to an external mechanical hard drive which can be quicker than downloading/installing them again, but they can't be run or updated when stored there. Standard Xbox One BC games will from an external hard drive as they did on the Xbox One.

Hi,

Current external hard drives are USB 3.0 5,400 RPM mechanical hard drives. These drives are very slow compared to the Expansion card. You won't be able to run Series X/S games from current external hard drives, not even the 2.5" external SSD drives either.
But, you will be able to archive your Series X/S games to these drives to save downloading again.

The expansion card can run all compatible Xbox games. Which will be Series X/S, Xbox One and the BC Xbox 360 and original Xbox games on the BC list.

Xbox One and other Backwards compatible games will load a lot faster on either the internal storage or the expansion card than they would if you ran them off your external hard drive.

Microsoft has a video on YouTube showing 'The Outer Worlds' loading in just 11 seconds on a Series X/S SSD, compared to nearly 60 seconds on Xbox One.

I see. So how would i be able to transfer everything i have on my old hard drive to the new expansion card?

One thing I personally cannot say for certain is if those games loading from the external hard drive will run the same way they would if they were installed straight onto the console...

If you load games on the Series X or S from an external hard drive they will load the same as they do on a regular Xbox One. There won't be any performance issues. Games installed on a external SSD (SATA SSD not the Expansion Card) will load faster then
they would before due to the much faster I/O on the Series X/S.

If you move your games to either the internal storage or the optional Expansion card, you will see significant loading speed improvements. They'll be massive on a game such as Odyssey. Fast traveling in 5 seconds rather than 40 on a regular Xbox One or One
X!

To use the Series X/S 'Quick Resume' on Xbox One or other BC games will require said games to be installed internally or to the Expansion Card. Series X/S games can only be installed on the Internal or Expansion card.
