Guys Pre-ordered Windows 7 Home Premium Edition, I have also treated my self to two shiny new WD Caviar Black 640GB's. Which after, and through alot of research I settled for them. I prefer the 320GB platters, compared to the three 250GB of the 750GB Blacks (about the same price) and I could not afford two 1TB drives! I am thinking about installing my new OS (when it arrives at the end of Oct) on the new drives striped in RAID 0. Couple of questions how reliable and stable is a RAID 0 configuration? with it not being true RAID? Will I benefit much from it? Should I just go for the one HDD? and return the other? I will leave my existing HDD Deskstar 500GB with XP on it, and have the dual boot option on startup, I will also use some of this drive to backup. Thanks in advance.
