I would really like to get a 500gb drive for my laptop, I only trust WD, and would like the enhanced specs of the scorpio black (7200rpm, larger cache, etc) over the blue. Is this drive in the works? Im tempted to buy a 7200rpm hitatchi off of newegg that has good reviews but I have had all WD drives until now and not one failure so Im pretty loyal at this point. any news on if this is gunnahappen?
