the reason why "green" drives arent good is because green drives are usually 5400rpm hdd's. the rpm decides how fast the hdd can read info, so if you stored like say games in there, your games will have longer loading screens, which is totally against what a gamer would normally want. green drives are more pointed towards storing movies and pictures and not programs.
price wise for 2 tb drives that arent green, choices would be like
this, or
this if one was on a really tight budget and will take the risk of a possible hdd failure due to quality not being as high as the ones near the 200$ mark.
