help needed with raid 1
right now i have 2 80gb sata hd's (no raid). i'm windering if i can mirror both of them on a 250gb. i'll set up 2 80gb partitions (although each partition would have several partitions within it) for each drive on which to mirror to. now my questions:
1. if i got a hd bigger than 160gb, would i have the remaining hd space, aside from the 160gb mirrors, for more storage?
2. say one of my 80gb hd's off which i boot my pc from fails. will i automatically be able to boot off the correct partition on the other hd?
i have some more, but can't remember them...
i'd probably get a 250gb hd for the mirror.
