The whole code works, my only concern here is that nothing enforces the class using this trait to have a DISK property. Do you have any better idea how to enforce the consuming class to have the property this needs? If not feel free to merge this PR as is.

How about that instead?
A default for a default...

Nope, it won't work, as we will still get an error due to constant self::DISK not existing.
I do not see any nice way to solve this, but I do not think that it is a big issue.
