Ok well I am currently upgrading my computer like many of you on this board. I am just curious as to where people would install their OS? the new system i want to build will have 2 WD 80g PATA hard drives (from old computer) and I am buying 2 Seagate 200g SATA Hard drives. Where would you recommend that I run my OS from? Is it worth Raiding any of these drives?
