Hi, I am going to upgrade my computer. I got a core i7 and have never got it over 50% usage but my ati 3 series graphics and hard drive are letting me down. I was wondering which would be better a 150GB VelociRaptor, Crucial M225 64GB, Intel X25-M 80GB or another one? I want the fast load times and I don't really write large files to the hard drive unless I'm converting video. Will 64GB be enough? All I will need to store is windows 7, office 2007, visual studio pro, 10GB of music and perhaps a game, the rest I can use my external esata drive for. Which one would you recommend for my needs? I also noted the crucial drive has a 5 year warranty and I could maybe stretch for the 128GB version of it.
