I just installed my new WD Scorpio 320gb 5400rpm HD the other day (as well as 4gb of ram a few days earlier) and have had no problems with either installation. However, my MBP is taking significantly longer to boot up. 1 minute and 10 seconds to be precise. Prior to installing the HD it took around 40 seconds. I was under the impression that the WD Scorpio was speedy and would not lengthen my boot up time. Even the tom's hardware laptop HD tests say that my new drive is all around better than my old stock 160gb HD. I've looked at system preferences -> accounts -> login items and the list is as bare as could be. Is there any way to reduce my boot up time?
