I'm about to purchase a Macbook Pro. Here is the spec I'm looking to purchase. 17" 3.06 Core Duo 4 GB memory 500 Serial ATA 7200 rpms Anti Glare Coating I'm debating whether I should get the 256 SD drive? It's obviously have the 500 GB. I plan on using my MacBook pro for Photography and Video editing so I'm wondering if there is a H U G E boost in HD performance from SD to 7200 rpm. I know that Sd is better but is it worth the price paying for that for my purpose and for that much SD space (256). I want to hear from people who actually was in the same situation I am in now in deciding between the two. Memory, I can always upgrade on my own?
