I want to install Win 7 Pro 64bit on a single Raid enabled Ocz Vertex Turbo ssd, & then expand my C drive to include my WD 750Gb RE3 hdd. Or could I make my WD hdd a D drive ? I also have 2 additional single HDDs with raid enabled containing Vista 64bit & XP Pro 32bit so my bios has IDE configured as Raid. I'm using the WD 750 Gb for Win7 RC now but wanted to add the ssd for the win7 os with the 750 for storage, I'm just not sure if Raid will let me add the 750 as a D drive for storage.
