^Yes, can support 2TB or more. BUT NOT IN RAID 0.
you're just plain wrong. check your facts. explain to me how i have a 6tb raid array in windows running right now.
intel places an artificial limit on array size in their chipsets that set at 2tb, and it's got nothing to do with RAID 0, it's on all raid levels. donno about amd's chipsets.
if you've got a raid solution that says it supports 2tb + and you partition it GPT, you're good to go, in vista as well.
personally i'd go with raid 1 if you're not going to miss the capacity provided by the extra drive.
