I'm just dealing with a not very good experience with a Segate 500GB internal hard drive. Rather than repeating the same mistake again, I'd like to know what is out there that people are having great experiences with. I want to use it for all of my photos and videos. (iLife '08, Photoshop, iMovie '08, AVCHD video editing, etc..) in Leopard. The Seagate I'm trying (ST3500630AS) from Newegg works, but not particularly well. It's noisy, slow, and it spins up even when I'm not using it. There must be a better solution, something comparable to what came with my Mac Pro. Does it make more sense just to buy one 750GB drive and put everything on one drive? Right now I only have a total 200GB in use, but now that I'm working with HD video hard drive space will begin to get gobbled up at a much quicker pace. Thanks for your suggestions.
