I was looking at raid cards recently and I'm not sure what to get. I'd like it to have 8 or more sata ports on it. The most important thing I need is the ability to break the 2TB disk size limit. I don't want to carve 2TB disks out of my space, I'd like to have it all displayed as one. So if I have 5TB usable space, I have one 5TB drive not, two 2TB and one 1TB drives. I'm having trouble finding information related to this. Doesn't have to be high end or super fast. Just allow large raids and be reliable. I have a RocketRaid 4 port right now and I don't know if my 32bit OS is limiting it or if the card is limiting the space to 2TB. Educate me please and thank you. 32 or 64 bit OS? High end raid card, or simple card with enough ports? Can't be done?
