Hi folks, If my memory serves me I have 4 Sata ports on the MB Sata Raid1, Sata Raid2, Sata1, Sata2. Currently I have: 1) Two Raptors paired up as Raid=138gig after format for C drive 2) Single Raptor=69.2gig after format for F drive 3) Hitachi=372gig after format for G drive These drives are going to be three years old this June. I keep all my data on the F and G drives. I need a larger C drive to work with snapshots from First Defence- ISR. I was thinking of taking the Raid setup and still use it but not for the C drive, now if I do that it looks like I would have to eliminate one (more like the Single Raptor 69.2gig) in order to purchase a new larger Sata drive for the C drive in order to accomodate the # of Sata ports the MB has. Tell me if I'm wrong? Or is there another way to make this work with out eliminating anything at all such as a Sata Card adapter. I was thinking of this drive for the C drive. Is this what they call Sata2 generation? I will attach a hardware report from Everest. I hope this is enough info. This MB is a revision 2 because the first one was replaced. That's all I was told. http://shop1.outpost.com/product/4697788?site=sr:SEARCH:MAIN_RSLT_PG Thank you for your help in advance.
