Currently I have a 640gb blue as my os, 2x1tb black as my secondaries and my 2tb green just came. Im thinking of moving my videos to my videos to my 2tb but I'm afraid of it crashing and would like to keep them on my blacks and raid 1 them but ot seeks pointless due to their performance, I'm thinking of maybe buying another 2tb and raid 1 them. or add an ssd as my primary and put the videos on my blue and clone a copy on my green ? What do you guys think?
