I'm stuck on which of these two drives to buy for my mid-2010 MBP. The Spinpoint uses two 500GB platters, which is good, but it is only 5400 RPM; that's a sticking point for me. The Seagate has a smaller capacity, but it's faster; speed is crucial for me. Here's my question: is there a major difference in the speed between the two? I use my MBP mostly for iPhoto (importing images from my DSLR), occasional video rendering (iMovie or Adobe Premiere), and Internet. Could someone give me their thoughts on which of these two drives would be the best? Or, if there are other suggestions, those are also welcome. Thanks!
