You do realize that you only have 3 options when buying HDD now right?
Seagate = Samsung = Maxtor (1 year warranty)
Western Digital = HGST ....so much HDD saturation that you have to solve a logic puzzle just to know if your drive can work in RAID (head parking issue). Not to mention that anything beyond their Black series is crap but its a premium price for 2TB HDD. (most of their drives are 1 year warranty)
Toshiba = Hitachi (Western Digital brought Hitachi then had to give the technology to Toshiba to prevent a monopoly) The current 2TB drives from Hitachi are 2 platter drives at 1TB per platter. I currently have 4 of their 2TB PH3200U drives which run great and cool. No complains (3 year warranty). My 4 Seagate 2TBs however, the bad sector count above 300 per drive. (1 year warranty).
So choose your poison. 2TB with 3 year warranty for less than $100 seem like a killer to me.
