What's the speed of the hard drive of the Xbox One X?

Yes, it's 5400 rpm. You can check this tear down video https://www.youtube.com/watch?v=Y__r8UjVvzY

The xbox one x has a 1TB 7200 rpm hard drive and it is not user replaceable.

I appreciate the Xbox One X must be faster at loading games but the Xbox One's speed is fine to me.

The loading speeds of the One X are no better than any other Xbox One as they used the same hard drive...it used to take upwards of 2 minutes for my one X to load a particular game!! You aren't missing out there. The One X is really only if you want the 4k content

Hi,

No, sorry it won't work. The USB ports on the Series X|S are USB 3.1 which have a maximum speed of 500MB/s. This means, no matter what drive you buy, no matter what speed it's rated at, you're stuck at the max speed of the USB port.

The only drives that can be used for Series X|S games are either the internal or the storage expansion card.

I have the Expansion card for my Series X. I also have an external 2TB USB SSD in an enclosure. I can only use the external SSD for Xbox One games. They do load a lot faster than a mechanical hard drive, but I can't play my Series X games off it.

All modern console whether it`s an Xbox or a PlayStation download and install games to the hard drive.

What is your internet connection speed? As this will directly affect how long it takes to download games.

Just be thankful you are not downloading Halo 5 onto a One X, as that is a massive at 107GB.
