PS4 CUH-2016A and CUH-2016B?

What is the difference of the above versions? Both are a slim, but I find nowhere exactly a difference

The PS4 CUH-2016A only has a 500GB hard drive, while the CUH-2016B has 1TB. The former is also available in several colors, the CUH-2016B's only in black, as far as I know.

Here's a list of all versions: http://www.gamona.de/games/ps4,tech-guide-modelle-unterschiede-der:article.html

Hope it helps!
