Not sure about Xbox because I haven't owned it in a while but PS4 lets you copy your system drive to a new drive pretty easily. The function is even built into the OS. I switched out the hard drive to an SSD using this technique.

It only works as long as the console is signed into the same account as used on the original hard drive.
If I had a physical disc, I could just buy another when it goes bad.
