HDD RMA Experiences

What are all of their colors, and how are they arranged – meaning, which color is their basic model, and which color is their flagship model, and where do the other colors fit in?

red pro is high quality server drive. Black is fast and high RPM for PC. Blue is standart PC usage. Green for archive.

Bad thing for me is warranty cropped. The new drive is now guaranteed for just 1 year.
This is very bad. I bought this driver and it only worked for 2 weeks.
