Help with hdds

hey need some help i got a WD 1tb black and it full so i going to a 2 tb black drive but for now if i got a green drive to make room in my black drive will it work only music and videos etc. would this slowdown my pc down stuff like that  


slower is a big word though. as the files are decently sized you generally end up with 80-90 MB/sec of copy actions a bit slower with MP3's but nothing to be of concern though.

Personally I would just stick with the green.
