I have a couple questions....I'm looking to upgrade my Macbook's RAM and hard drive, and need some advice. I have a Black 2.4GHz Macbook(bought July/August of 2008), and want to know if this RAM is compatible with it. As far as I can tell it is, and it is an insanely good deal, so I can't easily pass it up. My second question is about the HDD. I currently have the standard 250GB HDD, and want to upgrade to either the Seagate/Western Digital 500GB internal HDD. First....which is better, second....if I bought the Seagate there's a bundle that also comes with an enclosure that I could use for my current HDD for backups/extra storage.....but it's only USB, so is that fast enough? Thanks.
