Hi all. I am going to buy a new hard drive for my laptop Pavillion dv6 1205ee. My original hard drive is Momentus®5400.6. The two drives I am considering to buy are the WD Black ( WD7500BPKT) mentioned as Scorpio black and WD Black ( WD7500BPKX) mentioned as Western digital black on Amazon. Both drives are 750 gigs and with pretty much the same features.The only difference I could spot is 3 gb/s and 6gb/s interface. So I am confused about which one should I go for? Although the scorpio drive was announced earlier its slightly more expensive. Is it because its performance is better?
Please share your opinions as I need to replace my failing drive soon.
