What is the difference between WDBGPU0010BBY and WDBCFF0010BBY?

Question like in the title. Thank you very much!


On the official WD Support site, I could not find any information about the model number WDBCFF0010BBY.

Could be a European version since I found it on a Germany web site.

When I type the number in the search field on the german WD-site, I get two results, but when I click on it, the next page is the product catalogue and there the number can’t be found.
Could it be it is an older version, that no longer is listed, but still somewhere in teh cache on WD’s-site?
