Hi. I have a 13" MBP (mid-09) with a 2.26ghz C2D, 4gb ram (just upgraded) and 160gb hdd. I am thinking of swapping out the existing hitachi drive for one with better performance and capacity. An SSD is out cos of the price. I am considering the WD Scorpio Black 500gb 7200rpm HDD. Does anyone have this and how does it fare? What other alternatives should I consider? I've heard good things about the Seagate Momentus 7200.4 too. Any help will be appreciated. I intend to use Disk Utility to copy my OSX partition over, and use Winclone to copy my Win 7 32bit bootcamp partition.
