I got the 2009 Unibody MacBook and the 250GB 5400rpm HDD that came with it seems very slow to me. When I boot up and try to open applications for the 1st time is horrible! Opening a simple .pages file with the '09 Pages takes many seconds. I have it loaded in the RAM right now so I can't say how many seconds, but I would guess something like 20 to 30 secs. Loading everything that is not in the RAM is pretty slow. For example trying to search things with spotlight, or even opening the dashboard. Is this normal? I mostly use desktop computers and their HDD look MUCH quicker than this. There is that big of a gap between a 7200rpm 3.5" vs 5400rpm 2.5"? And if there is, would make a good performance difference if I bought a 2.5" 7200rpm for this MacBook? Thank you.
