I just bought 1 36.4 GB SATA 10k RPM HD, and a 74GB HD of same specs. I originally wanted to install them under a RAID 0 config, but I am not big on the fault issues and chance to lose data. So, I was going to install my smaller HD as one for the OS and key files, and use the 2nd HD to install my most used programs (mostly games) and data. First, with both of these HD's being new and clean, how should I go about installing them? I have installed single IDE HD's before. I just am not sure about using 2 HD's. My MB does have two SATA ports so I will not be piggy backing any connections on the MB. I know just enough about jumpers to do something stupid too. On a side note, is it possible for me to have my OS on 1 HD, and put programs on the second HD? If so, is that a good idea for performance and stability? Or is it better to keep the programs and OS together on 1 HD? Any help is greatly appreciated. And I do know more than I may make it sound-I am just trying to learn from the past when I have made mistakes and wished I had asked someone first. Basically, if you had these 2 HD's, what setup would you do, and how would you go about installing them?
