Re: Question about OS migration from 1 HDD to a RAID system.
No, RAID 0 doubles your storage, RAID 1 halves it.
RAID 0 = Striping - data is stored half on one drive, half on the other, you are effectively doubling your space.
Problem? Lose one drive, lose everything.
RAID 1 - Mirroring. Second hard drive simply mirrors all write operations and aids in read operations - if its a decent RAID system, if you lose one drive, nothing happens and you keep on trucking.
To do what OP asked will require some kind of disk imaging software like Norton Ghost and then the key is making absolutely sure Vista has the RAID drivers required otherwise it'll just blue screen when it starts to boot.
