I for one would avoid any "green" drives (or similarly called: the ones with lower spindle RPMs and spinning down when unused). In addition to their behavior, they are designed for "light use" consumer market, so I wouldn't be surprised if they have noticeably lower longevity. I usually use HGST (formerly Hitachi, before that IBM); - He filled and sealed ones sound really good (we will know statistics on them some 5-7 years down the road, so now we can only guess). Someone may list good ones made the their competitor Seagate. I hope, this helps.
