    Hello. I am looking at making my first Mac purchase. I plan on getting a 15" MBP and am debating between the standard 500GB HD and the 7200rpm 500GB HD. Is there much performance difference? Also, what impact does this have on battery life (I'd imagine it would shorten it at least a bit)? Any advice is much appreciated!

    It will shorten the battery life by ten to 20 minutes, depending on the capacity of your battery. A 5400RPM HDD will have speeds of up to 75MB/s, though the higher the capacity, the faster it is, but my 5400RPM 500GB S-ATA HDD got 75MB/s in HDD speed benchmarks.
    The 7200RPM HDD will have a maximum speed of 95MB/s.

    So an SSD would basically be about twice as fast as the 7200rpm HD?

    If not even more, as many SSDs offer speeds of more than 200MB/s in read and write actions.

    SSD is the way to go if you have the money because they are faster and more power efficient. Otherwise, I'd always got with a 7200RPM drive over a 5400RPM, I did not notice a conscious difference between having a 5400 and a 7200 RPM drive in my Spring 2007 WhiteBook. I'm sure it made a difference, but not a battery difference I could even notice. The speed improvements are noticeable though.

    How much more efficient is an SSD than an HDD in terms of battery life -- in % terms.
