I need suggestions, WD blue or green? I have a Samsung ssd for OS. I need secondary hdd for storage of various media. Will it take time to load media if I chose WD green for storing, lets say movies?
Yes, using a WD Green is going to cost you some time when transferring or loading files. It's designed to be efficient, not fast. The same thing can be said of the Blue, but based on benchmarks the Blue is much faster. In fact, the Blue doesn't lag behind the Black by much.
Go with the Blue. It's not as Earth-friendly, but it will be better for your blood pressure.
