I am interested in getting a hard drive upgrade for my 3.5 year old 2.4 GHz MacBook Pro. Right now I am mostly wondering what everyone's opinions are of Seagate vs. Western Digital? I've heard that the Seagate's are much quieter, but I am seeing much better reviews for the WD. This is the one I am looking at. Any advice anyone can give me would be amazing. http://www.tigerdirect.com/applicat...?EdpNo=6449957&csid=ITD&body=MAIN#detailspecs Thank you!
