Hi, I want to buy HP Pavilion zd8185EA it is expensive maschine but I am not impressed with the HDD speed and I dont know if it makes a big difference. So if someone has knowledge about this it would help me. And can it be exchanged or I could add a external hdd with 7200 rpm which i would use for stuff which needs speed? Or is it a stupid idea. 
Thanks very much for every help.
