Read some reviews and decide. My suggestion: WD Black 3 TB SATA Hard Drives ( WD3001FAEX) The WD RE drives are enterprise quality and accordingly higher priced.
but red and black both,from WD are not perfact model of hdd. they also have fail complaints.
You are right, Udit! All HDDs will eventually fail. I have had good luck with WD RE drives (enterprise quality) that I use as my C: drive. For data I use WD Black, or Seagate, after reading reviews and customer feedback.
