I'm looking for better user interface speed. I just bought an Asus 2.5 gighz quad core 8gig tower. I heard recently that a 10000 rpm drive and/or raid setup can increase program startups by a lot. I'm assuming I have a 7200 rpm drive or such. I don't like any lag time and am looking for the best solution. I've done a little research and have found the Cheetah 15k rpm drives but it looks like their access times and mb/s times are not nearly as good as some others I've ran into and supposedly they're supposed to be the best as of right now? I'm not understanding all these specs and what exactly I need. I have 6 sata hookups that I can use on my mother board. Any suggestions?
