Hi Guys, About to order either a i5 or an i7, though not sure if I should go with the 2TB HD. I think i read that the 1TB models were WD Black, can someone confirm this. Also what brand/type is the 2TB drive on the i5/i7 models. In one thread someone said they got a Hitachi drive, although that was a core duo, though probably the same drive as in the quad cores. If they were the 2TB WD blacks I would consider the 2TB upgrade to be good value. One, more thing, if the 1TB is the WD Black, what is the noise level? any ticking noises? Thanks.
