mmm My current 6x1tb's in raid are fine, along with another 3x 1tb's in my media.. and a 500gb torrent drive that has been smashed for the last 36 months. They are all going strong still. The reason I asked was around the head parking, and issues it may cause. as they will run 24/7 and no doubt always be spinning I dont think it'll be a issue at all. http://www.umart.com.au/pro/products_listnew.phtml?id=10&bid=2&id2=129 The prices for all the 2tb's in the low end are similar, so some seagates or WD's would be my pick, unless someone can prove they are slower or inferior.
