I've got a 5400rpm HDD in my MacBook Pro -- see specs below. I really didn't think much of the slower speed compared to a desktop being a big deal back in the day, but now I'm thinking it is. It seems that many things across the board take a little longer to launch or load. I probably ruined my perception of speed by using my dad's brand new iMac, but I don't think my computer should trail his that much on just opening iPhoto or Safari. The lateral move on storage space -- keeping 320GB but bumping to 7200rpm -- would cost me about $90. I don't think a 500GB 7200rpm drive exists. I also don't want to drop $500+ on a SSD because I really can't and I might as well buy a Mac Mini at that point. Sooooo I'd appreciate any first-hand advice, or even third-hand advice.
