I have a Macbook with the factory 120GB hard drive. After about 7 months of use I'm almost out of space (11GB remaining) so a hard drive upgrade is going to be necessary. However, I've reached a dilemma. Should I upgrade to a 250GB HDD at 5400RPM or a 200GB HDD at 7200RPM? I wouldn't mind having the extra 50GB, but I don't know if I'll need it any time soon. Is there a truly noticeable difference in speed between the two? The 250GB drive is considerably cheaper ($114.99 v. $179.99), but the speed boost would be nice. Here are the drives that I'm looking at: http://www.newegg.com/Product/Product.aspx?Item=N82E16822145160 http://www.newegg.com/Product/Product.aspx?Item=N82E16822152094 Also, if you know of any good deals on drives feel free to post them!
